Description

Technical Field

[0001] The invention relates to an automated food production technology, in particular to a leather roll forming device and a leather roll continuous production line. Background Art

[0002] The leather roll is made by winding two or more groups of leather materials, and can only be sold after being cut into rolls of predetermined length. In the prior art, the front end of the leather is fixed on a rotating device, and the rotating device winds the leather materials together during the rotation process. In this process, the operator must maintain a standing posture and hold the leather materials, which is labor-intensive and has low production efficiency. In addition, in this production method, hooks must be set at both ends of the leather roll to ensure that the leather materials are wound together by fixing the position of the hooks, and then dried and shaped. The leather roll after drying and shaping will then complete the cutting step. After cutting, the leather roll near the hook will be wasted, with waste reaching 5%. In mass production activities, 5% of waste will cause corresponding profit losses. Therefore, the prior art needs to be further improved. Summary of the invention

[0019] The present invention realizes continuous feeding and pressing during the leather coil winding process, eliminates waste, and greatly improves production efficiency. In order to more clearly explain the advantages of the present invention, some specific details of the present invention are recorded in the following description.

The present invention realizes continuous feeding, winding, pressing and shaping, and discharging, so as to achieve the purpose of continuous and automatic production of leather rolls.

[0022] Preferably, the transmission assembly 300 includes an axial transmission mechanism 310, a reversing transmission mechanism 320, and a longitudinal transmission mechanism 330. The driving assembly 200 drives the winding assembly 400 to rotate via the axial transmission mechanism 310, the winding assembly 400 drives the longitudinal transmission mechanism 330 to rotate via the reversing transmission mechanism 320, and the longitudinal transmission mechanism 330 drives the die assembly 500 to rotate. The axial transmission mechanism 310 is, for example, a reduction pulley, and the reversing transmission mechanism 320 is, for example, a bevel gear set, which converts the axial rotation of the winding assembly 400 into a longitudinal rotation. The longitudinal transmission mechanism 330 is, for example, a chain wheel, which sequentially transmits the longitudinal rotation to different die assemblies.

[0023] Preferably, the winding assembly 400 includes an outer frame 410, a first sleeve 420, and a second sleeve 430, wherein the first sleeve 420 and the second sleeve 430 are coaxially arranged, the first sleeve 420 and the second sleeve 430 are rotatably mounted on a fixed bracket 700, the inlet and the outlet are respectively arranged in the first sleeve 420 and the second sleeve 430, and the die assembly 500 is mounted on the outer frame 410.

[0027] Preferably, the first groove 511 and / or the second groove 521 is provided with an anti-skid groove 523. The provision of the anti-skid groove 523 can prevent the first pressing roller 510 and the second pressing roller 520 from slipping on the leather roll, thereby ensuring continuous forming. Example

[0028] Different from the first embodiment, the die assembly 500 of this embodiment adopts a belt transmission structure. Figure 10 to Figure 11 The die assembly 500 includes an upper conveyor belt 550, a lower conveyor belt 560, a first die 551 fixed to the upper conveyor belt 550, and a second die 552 fixed to the lower conveyor belt 560.

Fig.12 As shown, the leather roll cutting device includes a cutting table 610, a length-fixing assembly 620, a cutter assembly 630, and a material-discharging table 640. After the leather roll enters the cutting table 610, the length-fixing assembly 620 measures the length of the leather roll. When the leather roll entering the cutting table 610 reaches a preset length, the cutter assembly 630 will cut it. The cut leather roll enters the material-discharging table 640, and the next section of leather roll enters the cutting table 610 again. This cycle is repeated to achieve continuous shaping of the leather roll.
