Description

Technical Field

[0001] This utility model relates to an upper pressure plate mechanism with a toothed conveyor chain. Background Technology

[0002] A toothed chain, also known as a conveyor chain with pointed teeth, is commonly used in leather forming equipment. The chain pierces the edges of the leather, carrying it along with the pointed teeth to achieve the conveying of the leather. There are two methods for conveying leather using a toothed chain: the first is where the conveyor chain supports the leather from below, as disclosed in patent document CN104828472A; the second is where the leather hangs from the conveyor chain, as disclosed in patent document CN106429207A. Regardless of the method, a pressing mechanism is needed to press the edges of the leather into the teeth of the conveyor chain. In the prior art, there are two designs: the first, as in patent document CN205240639U, uses a pressure roller fixed above the transmission gear in conjunction with a front-guided feeding plate mechanism to press the leather into the teeth of the conveyor chain; the second, as in patent document CN208843219U, uses the lifting and lowering of adjustable guide plates to press the leather into the teeth of the conveyor chain. In actual operation, neither of these two methods is ideal. In the first method, the interaction between the transmission gears and the pressure rollers is too forceful, and the material is easily damaged. In the second method, the operation of pressing the material requires electronic control, which makes the transmission control more complex and prone to errors at the electronic control level, such as failure to press the material in time.

[0025] Figure 2 An example of a toothed chain conveying mechanism is provided, including a conveyor frame and chain frames 100 disposed on both sides of the conveyor frame. The chain frames 100 are equipped with a toothed chain and a toothed chain sheet piercing and pressing mechanism 2. (Refer to...) Figure 3 and Figure 4 The toothed chain sheet piercing and pressing mechanism 2 is located above the chain bracket 19. When the toothed chain sheet piercing and pressing mechanism 2 is working, the toothed chain is located above the chain bracket 19 and supported by the chain bracket 19. Those skilled in the art will understand that, in another optional embodiment, the toothed chain sheet piercing and pressing mechanism 2 can also cooperate with the sprocket and be located above the sprocket.

[0026] 2. Toothed chain sheet material piercing and pressing mechanism, refer to Figure 1 and Figure 3 It includes a mounting bracket 21, a swing bracket 22, a pressure roller 23, and a spring 24.

[0027] Mounting bracket 21 is used to fix it to chain frame 100. In this embodiment, mounting bracket 21 includes a horizontal bracket plate 211 and a vertical bracket plate 219. The horizontal bracket plate 211 and the vertical bracket plate 219 are integrated to form an L-shaped structure. When the toothed chain material piercing and pressing mechanism 2 is installed on the chain frame 100, it is fixed to the chain frame 100 by bolts provided on the vertical bracket plate 219. The vertical bracket plate 219 is vertically positioned, and the horizontal bracket plate 211 is horizontally positioned.

[0028] One end of the swing frame 22 is mounted on the mounting frame 21 via a horizontal swing shaft, allowing the swing frame 22 to swing around the swing shaft in a vertical plane. Specifically, in this embodiment, the swing frame 22 is mounted on a horizontal frame plate 211 and includes a swing block 221. Two bearing blocks 212 are mounted on the horizontal frame plate 211. A swing shaft 229 is positioned between the two bearing blocks 212. One end of the swing block 221 is located between the two bearing blocks 212; the two bearing blocks 212 are located on opposite sides of the swing block 221. The swing shaft 229, which connects the two bearing blocks 212 of the swing block 221, is mounted on the horizontal frame plate 211, allowing the swing block 221 and even the entire swing frame 22 to swing around the swing shaft 229.

[0029] The pressure roller 23 is horizontally mounted on the swing frame 22, and has an annular groove 231 along its circumferential direction on its rim. Specifically, in this embodiment, the swing block 221 has a vertically penetrating pressure roller slot 2211. The two sides of the pressure roller slot 2211 are slotted side plates 2212. The pressure roller 23 is disposed within the pressure roller slot 2211, and its two ends of the shaft 239 are respectively mounted on the slotted side plates 2212 on both sides. The shaft 239 is horizontally positioned. The horizontal frame plate 211 has pressure roller holes corresponding to the pressure roller slot 2211, allowing the pressure roller 23 on the swing frame 22 to pass through the horizontal frame plate 211, so that a portion of the pressure roller 23 passes through the pressure roller hole and is located below the horizontal frame plate 211.

[0030] Spring 24 connects mounting bracket 21 and swing bracket 22, causing pressure roller 23 on swing bracket 22 to generate downward elastic force. Specifically, in this embodiment, horizontal frame plate 211 is provided with two vertical spring mounting posts 29. Each spring mounting post 29 includes a post body 291 and a spring locking block 292 located at the top of the post body 291. The spring locking block 292 is a protrusion with a diameter larger than that of the post body 291; it can be integral with the post body 291 or a component installed and fixed to the top of the post body 291. In this embodiment, the spring mounting post 29 is implemented using a large-sized smooth bolt. The spring locking block 292 fits onto the smooth portion of the smooth bolt and is in close contact with the pad at the head. Matching the spring mounting post 29, the swing bracket 22 also includes a spring wing plate 222. In this embodiment, the spring wing plate 222 is an integrally connected component with the swing block 221. There are two spring wing plates 222. Two spring wing plates 222 are mounted on the swing block 221, away from the swing axis 229, and are located on both sides of the swing block 221. The positions of the two spring wing plates 222 are matched with the two spring mounting posts 29, so that the two spring mounting posts 29 pass through the two spring wing plates 222 respectively. That is, the spring wing plates 222 are provided with through holes that match the column bodies 291 of the spring mounting posts 29, so that the spring wing plates 222 can move up and down along the column bodies 291. The spring 24 is mounted on the column body 291 and is locked between the spring locking block 292 and the spring wing plate 222, so that the top end of the spring 24 abuts against the spring locking block 292 and the bottom end abuts against the spring wing plate 222.

[0031] The working principle of this embodiment is as follows:

[0032] The toothed chain transmission mechanism in this embodiment is a toothed chain transmission mechanism with the teeth facing upwards. The teeth of the toothed chain located on the chain bracket 19 are directly opposite the groove 231 of the pressure roller 23. That is, when the toothed chain sheet material piercing pressure roller 2 is set on the chain frame 100, the pressure roller 23 is directly opposite the toothed chain on the chain bracket 19, so that the teeth on the toothed chain can penetrate into the groove 231 of the pressure roller 23. The toothed chain sheet material piercing pressure roller 2 is set at the outlet of the loading station 900 of the toothed chain transmission mechanism. In the loading station 900, after the sheet material is centered, both sides are pressed onto the toothed chain by the pressure rollers in the pressure roller assembly. At this time, the toothed chain does not pierce the sheet material. Through the frictional force between the toothed chain teeth and the pressure rollers, the movement of the toothed chain drags the sheet material to the outlet of the loading station 900. When the sheet material moves to the position of the toothed chain sheet material piercing and pressing mechanism, the pressure roller 23 of the toothed chain sheet material piercing and pressing mechanism, in conjunction with the spring force of the spring 24 and the support of the bottom chain bracket 19, continuously and uninterruptedly engages the edge of the sheet material with the teeth of the toothed chain. After the sheet material is subsequently pierced by the toothed chain, the movement of the toothed chain becomes the driving force for dragging the sheet material.
