[0001] The utility model belongs to the technical field of multi-roller calenders, and particularly relates to a safety protection device for a multi-roller calender. Background Art

[0002] In modern industrial production, multi-roll calenders, as a key processing equipment, play an indispensable role in numerous industries, including papermaking, printing, plastics, rubber, leather, and more. By leveraging the coordinated operation of its multiple rollers, multi-roll calenders can apply uniform and powerful pressure and friction to various materials, significantly improving their surface smoothness, gloss, and physical properties, meeting various high-quality production requirements.

[0003] However, the actual operation of a multi-roll calender presents a series of significant safety hazards. The roller assembly typically rotates at high speeds and exerts significant force. Because the rollers are fully exposed during operation, operators can easily inadvertently place a body part close to or even contact the high-speed rollers due to errors, inattention, or violations of operating procedures, potentially causing serious bodily injury or even life-threatening accidents.

[0004] Furthermore, in the working environment of a multi-roll calender, there are often various foreign objects such as debris, small tools, etc. If these foreign objects are accidentally caught between the rollers during operation, they will not only cause serious wear and damage to the rollers, affecting the accuracy and service life of the equipment, but may also cause the rollers to become stuck, equipment failure, or even more serious safety accidents such as sudden breakage and splashing of equipment parts, posing a huge threat to surrounding operators and equipment.

[0005] For example, a safety protection door device for a multi-roll calender described in the authorization announcement number CN214938777U manually lowers the safety door to lock it, and multiple components are set for locking. When opening, manpower is required to unlock the door and then raise the safety door. This method not only requires precise structural design, but also requires manpower to control the opening and closing of the safety door. At the same time, when the internal pressure rollers need to be inspected, the safety door is too small and may need to be disassembled during inspection, which is time-consuming and labor-intensive.

[0006] To this end, we propose a safety protection device for a multi-roller calender, which not only protects the calender but also has a simple structure, does not require manual operation, is convenient for maintenance, and saves time and effort. Utility Model Content

[0007] The purpose of this utility model is to provide a safety protection device for a multi-roller calender, which not only can protect the calender but also has a simple structure, does not require manual operation, is convenient for maintenance, and achieves the effect of saving time and labor.

[0008] The technical solutions adopted in this application are as follows:

[0010] Furthermore, two semicircular side protection plates are provided on the support platform, and the two semicircular side protection plates and the semicircular protection plate form a complete protection shell.

[0011] Furthermore, a smooth groove is provided on the semicircular side protection plate.

[0012] Furthermore, the pressure roller assembly includes three groups of symmetrical fixed plates arranged on the top of the support platform, a pressure roller is arranged between two of the fixed plates, and the pressure roller is driven by a first motor arranged on the fixed plates.

[0013] Furthermore, the rotating assembly includes a stepping reciprocating motor arranged on the support platform, the output end of the stepping reciprocating motor is installed with a rotating rod located inside the through slot, and the gear is fixedly sleeved on the rotating rod.

[0014] Furthermore, an arc-shaped sliding groove is provided on the inner wall of the semicircular groove, and an arc-shaped sliding block connected to the semicircular protective plate is provided inside the arc-shaped sliding groove.

[0015] The technical effects achieved by this utility model are:

[0016] When using this device, Figure 2 As shown, the rotating assembly is started, and the rotating assembly drives the gear to rotate inside the installation groove. Since the gear is engaged with the meshing teeth, the meshing teeth drive the semicircular protective plate to rotate inside the semicircular groove, so that the semicircular protective plate protects the pressure roller assembly, improving safety. When the pressure roller assembly needs to be operated, the rotating assembly rotates in the opposite direction, so that the gear drives the meshing teeth to make the semicircular protective plate enter the semicircular groove for storage, thereby facilitating human operation. This device not only protects the pressure roller machine, but also has a simple structure and does not require manual operation, achieving the effect of saving time and effort.
