Description

Technical Field

[0001] This utility model relates to the field of rubber calendering technology, specifically a calendering device for producing rubber pressure pads. Background Technology

[0002] Rubber calendering is a molding process that uses rollers to extrude and stretch rubber materials. By using the gap between two or more relatively rotating rollers, the rubber material is plastically deformed to produce sheets, cloths, or preforms of specific thickness, width, or surface patterns.

[0003] In the prior art, the authorized announcement number CN222875120U discloses a rubber calendering machine for producing infusion set float valves, including a machine body, wherein two sets of rollers are arranged on the inner side of the machine body for calendering the rubber raw materials required for producing infusion set float valves.

[0004] After being processed by calendering, the rubber sheets slowly fall into a hopper located below the pressure rollers. Due to the lack of precise positioning control during the descent, these rubber sheets often end up in a disordered and random stacked state after entering the hopper. Over time, the space inside the hopper is rapidly filled by the continuously falling rubber sheets, quickly reaching its capacity limit. At this point, to prevent the hopper from becoming overfilled and disrupting the smooth operation of the production process, workers must intervene to adjust and organize the rubber sheets stacked in the hopper. Furthermore, the rubber sheets themselves have a certain degree of stickiness, which makes them prone to sticking together during stacking, resulting in multiple rubber sheets tightly adhering together, increasing the difficulty of subsequent processing and sorting. Summary of the Invention

[0005] The purpose of this invention is to provide a calendering device for producing rubber pressure pads, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a calendering device for producing rubber pressure pads, comprising a calender frame, a calendering roller rotatably mounted inside the calender frame, a drive motor fixedly mounted on one side of the calender frame, a reduction gearbox fixedly mounted between the drive motor and the calendering roller, a material box slidably mounted at the bottom of the calender frame, rubber sheets stacked inside the material box, a guide mechanism mounted on the calender frame, the guide mechanism comprising a screw frame fixedly mounted on both sides of the calender frame, a reciprocating screw rotatably mounted inside the screw frame, a reciprocating slider slidably mounted inside the screw frame and connected to the reciprocating screw, and an anti-sticking mechanism mounted on the reciprocating slider.

[0007] Preferably, the guiding mechanism further includes a servo motor and a bearing housing fixedly mounted on the calender frame. A drive shaft is rotatably mounted on the bearing housing, and the drive shaft is perpendicular to the reciprocating lead screw. Helical gears are fixedly mounted on both the drive shaft and the reciprocating lead screw, and the helical gears mesh together in pairs.

[0008] Preferably, a bearing is installed in the bearing housing, the drive shaft is rotatably mounted on the bearing housing via the bearing, and a coupling is provided at the output end of the servo motor, with one end of the drive shaft fixedly mounted to the output end of the servo motor via the coupling.

[0009] Preferably, bearings are installed at both ends of the lead screw frame, the reciprocating lead screw is rotatably mounted on the lead screw frame via the bearings, and the anti-sticking mechanism is movably mounted below the calendering roll via a reciprocating slider.

[0010] Preferably, the anti-sticking mechanism includes a mounting plate fixedly installed on the reciprocating slider, storage boxes are fixedly installed on both sides of the mounting plate, a powder outlet is opened at the lower end of the storage box, a transfer roller is rotatably installed in the powder outlet, and a sealing cover is connected to the upper end of the storage box, and a buckle is installed on the sealing cover.

[0011] Preferably, a hinge is installed at the upper end of the storage box, and the sealing cover is installed at the upper end of the storage box via the hinge.

[0012] Preferably, the storage box contains talc powder, and the powder outlet has rotating grooves at both ends, with the transfer roller rotatably mounted inside the powder outlet via the rotating grooves.

[0013] Preferably, the sealed box cover is fixedly installed on the upper end of the storage box by a snap fastener.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the rubber sheet falls and passes through the gap between the transfer rollers, the servo motor can be started. After the servo motor is started, it will drive the drive shaft to rotate, which in turn drives the reciprocating screw to rotate. The rotation of the reciprocating screw will drive the reciprocating slider to move back and forth. The back and forth reciprocating motion of the reciprocating slider will drive the two transfer rollers to move back and forth, thereby guiding the falling rubber sheet to be neatly stacked in the material box, thus reducing the labor intensity of the workers.

[0015] 2. In this application, after opening the sealed box cover, talc powder can be stored in the storage box. When the transfer roller guides the rubber sheet to fall, the transfer roller will rotate due to external force. During the rotation, the transfer roller will transfer the talc powder in the storage box to the surface of the rubber sheet. The talc powder transferred to the surface of the rubber sheet can form an isolation layer, thereby preventing the rubber sheets stacked in the hopper from sticking together.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a calendering device for producing rubber pressure pads, including a calender frame 1, a calendering roller 2 rotatably installed inside the calender frame 1, a drive motor 4 fixedly installed on one side of the calender frame 1, a reduction gearbox 3 fixedly installed between the drive motor 4 and the calendering roller 2, a material box 5 slidably installed at the bottom of the calender frame 1, rubber sheets 8 stacked inside the material box 5, a guide mechanism 6 installed on the calender frame 1, and an anti-sticking mechanism 7 installed on the reciprocating slider 607.

[0020] Specifically, the operation of the drive motor 4 effectively drives the calendering roller 2 to rotate. When the calendering roller 2 starts to rotate, it applies a certain pressure and friction to the raw rubber placed on it, thereby performing uniform and continuous rolling treatment on the raw rubber. In this process, the raw rubber is gradually stretched and thinned under the action of the calendering roller 2, and is finally processed into a rubber sheet 8 with a certain thickness and uniformity. The guiding mechanism 6 can guide the falling rubber sheet 8 to be neatly stacked in the material box 5, and the anti-sticking mechanism 7 can prevent the rubber sheets 8 stacked in the material box 5 from sticking together.

[0021] Example 2: Figure 2 and Figure 3 As shown, the guide mechanism 6 includes a screw frame 602 fixedly installed on both sides of the calender frame 1. A reciprocating screw 606 is rotatably installed inside the screw frame 602. A reciprocating slider 607 is slidably installed inside the screw frame 602 and connected to the reciprocating screw 606. The guide mechanism 6 also includes a servo motor 601 and a bearing seat 604 fixedly installed on the calender frame 1. A drive shaft 605 is rotatably installed on the bearing seat 604 and is perpendicular to the reciprocating screw 606. Helical gears 603 are fixedly installed on both the drive shaft 605 and the reciprocating screw 606 and mesh together in pairs. Bearings are installed inside the bearing seat 604, and the drive shaft 605 is rotatably installed on the bearing seat 604 through the bearings.

[0022] Specifically, when the rubber sheet 8 falls, it passes through the gap between the transfer rollers 704. Then, the servo motor 601 can be started. After the servo motor 601 is started, it will drive the drive shaft 605 to rotate; after the drive shaft 605 rotates, it will drive the reciprocating screw 606 to rotate; after the reciprocating screw 606 rotates, it will drive the reciprocating slider 607 to move back and forth; after the reciprocating slider 607 moves back and forth, it will drive the two transfer rollers 704 to move back and forth, thereby guiding the falling rubber sheet 8 to be neatly stacked in the material box 5, reducing the labor intensity of the workers.

[0023] Example 3: Figure 2 and Figure 4 As shown, the anti-sticking mechanism 7 includes a mounting plate 706 fixedly installed on the reciprocating slider 607. Storage boxes 701 are fixedly installed on both sides of the mounting plate 706. A powder outlet 703 is opened at the lower end of the storage box 701. A transfer roller 704 is rotatably installed inside the powder outlet 703. A sealing cover 702 is connected to the upper end of the storage box 701. A buckle 705 is installed on the sealing cover 702. A hinge is installed at the upper end of the storage box 701. The sealing cover 702 is installed at the upper end of the storage box 701 through the hinge.

[0024] Specifically, the sealing lid 702 can be opened, allowing talcum powder to be stored inside the storage box 701. Subsequently, when the transfer roller 704 begins to guide the rubber sheet 8 downwards, the transfer roller 704 is inevitably forced to rotate. It is during this rotation that the talcum powder pre-stored inside the storage box 701 is effectively transferred to the surface of the rubber sheet 8. This transferred talcum powder quickly forms an insulating layer. The main function of this insulating layer is to effectively prevent the rubber sheets 8 stacked inside the hopper 5 from sticking together, thus ensuring that the rubber sheets 8 remain well separated during storage and handling.

[0025] Working principle: The drive motor 4 drives the calendering roller 2 to rotate, which rolls the raw rubber and stretches it into a rubber sheet 8. The calendered rubber sheet 8 falls into the material box 5. As the rubber sheet 8 falls, it passes through the gap between the transfer rollers 704. Then, the servo motor 601 is activated, which drives the drive shaft 605 to rotate. The drive shaft 605 then drives the reciprocating screw 606 to rotate, which in turn drives the reciprocating slider 607 to move back and forth. The reciprocating slider 607 then drives the two transfer rollers 704 to move back and forth, thus guiding the falling rubber sheet 8 to be neatly stacked in the material box 5, reducing the labor intensity of the workers. After opening the sealed box cover 702, talc powder can be stored in the storage box 701. When the transfer roller 704 guides the rubber sheet 8 to fall, it will be forced to rotate. When the transfer roller 704 rotates, it will transfer the talc powder in the storage box 701 to the surface of the rubber sheet 8. The talc powder transferred to the surface of the rubber sheet 8 can form an isolation layer to prevent the rubber sheets 8 stacked in the material box 5 from sticking together.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
