Technical Field

[0001] This utility model relates to the field of material processing equipment technology, and in particular to a rubber strip slitting machine. Background Technology

[0002] In the manufacturing process of some silicone rubber products, silicone rubber strips are often used. These strips are usually made by extruding hot-melted rubber into sheets and then cutting them. The cut strips are then transported to the next processing station by conveyor belts and other transportation devices.

[0003] To facilitate feeding, the feed inlet of the rubber strip slitting machine is usually set as an open opening or a feed hopper with an opening at the top. However, such an open feed inlet or an opening hopper at the top is prone to contamination of the rubber material by falling dust and impurities during the filling process, so it needs to be improved. Utility Model Content

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-6 The image shown is an embodiment provided by this utility model.

[0023] This utility model provides a rubber strip slitting machine, including: a slitting machine body 10 and a dust cover 20. The top of the slitting machine body 10 is provided with a feed inlet 11, which is square. The dust cover 20 is a cuboid with an open bottom and covers the feed inlet 11 to protect it. A feed window 21 is provided on one side wall of the dust cover 20. In order not to reduce the feed area, the feed window 21 is formed by cutting off the entire side wall. A baffle 22 is adapted to be installed inside the feed window 21. The size of the baffle 22 matches the size of the feed window 21. In order to save materials, the baffle 22 can be processed from the cut-off side wall. At the same time, in order to facilitate the movement of the baffle 22, the width and height of the baffle 22 can usually be set to be 5-10mm smaller than the feed window 21. Specifically, the dust cover 20 has two support strips 23 on the inner walls on both sides of the feed window 21. The two support strips 23 are symmetrical and extend horizontally from the outside to the inside. The outer ends of the support strips 23 are close to the sides of the feed window 21. The length of the support strips 23 is at least more than half the height of the baffle 22. The back of the baffle 22 can abut against the top of the two support strips 23. The two support strips 23 support the baffle 22 from both sides, so that the baffle 22 will not fall off and can slide back and forth along the support strips 23. The baffle 22 can be pushed in or pulled out like a drawer. In addition, corner limiting posts 231 are respectively provided at the outer ends of the two support strips 23. The corner limiting posts 231 are cylindrical strips provided at the corners of the outer ends of the support strips 23. The axis of the baffle 22 is the same as that of the baffle 231 and parallel to it. Correspondingly, limit hooks 221 are provided on both sides of the back of the baffle 22. The two limit hooks 221 can be hooked with the corresponding corner limit posts 231. After the limit hooks 221 are connected to the corner limit posts 231, they can rotate around the corner limit posts 231, thereby allowing the baffle 22 to rotate around the axis of the corner limit posts 231. With the cooperation of the limit hooks 221 and the corner limit posts 231, when the baffle 22 slides to the outer end of the support strip 23, it will not only not disengage from the support strip 23, but can also turn with the help of the corner limit posts 231, so that the baffle 22 changes from a horizontal sliding mode to a rotation mode around the axis. When the baffle 22 is not subjected to external force, such as Figure 5 As shown, it can be hung vertically inside the feed window 21, blocking the feed window 21 to the maximum extent. When feeding is needed, simply push the lower end of the baffle 22 inward to let the rubber material be put into the feed inlet 11 from the side. When the equipment is shut down or needs cleaning and maintenance, such as Figure 4As shown, the baffle 22 can also be horizontally stored inside the dust cover 20. After adopting the above-mentioned rubber strip slitting machine, the dust cover 20 set outside the feed inlet 11, together with the feed window 21 set on the side wall of the dust cover 20, can also cover the top of the feed inlet 11 during feeding, which can greatly reduce or avoid the contamination of the rubber material by falling dust and impurities during the filling process. Furthermore, the baffle 22 set inside the feed window 21 can further reduce the exposed area of ​​the internal rubber material during feeding, reducing the entry of falling dust.

[0024] Furthermore, both the dust cover 20 and the baffle 22 are made of transparent or semi-transparent materials, such as PC plastic, acrylic or resin materials, so that the dust cover 20 can block the falling dust without obstructing the view and affecting the staff's observation of the remaining amount and condition of the rubber material in the feed port 11.

[0025] Specifically, the height of the baffle 22 is less than the width of the inner top wall of the dust cover 20, so that when the baffle 22 slides inward along the support strip 23 to the innermost end, it can be completely retracted into the dust cover 20.

[0026] Specifically, the support strip 23 is positioned close to the inner top wall of the dust cover 20, and the height difference between the top of the support strip 23 and the inner top wall of the dust cover 20 is greater than the thickness of the baffle 22. This allows the baffle 22 to be clamped between the support strip 23 and the inner top wall of the dust cover 20, which can both limit the position of the baffle 22 and raise the position height of the rotation axis of the baffle 22, thereby maximizing the swing range of the lower part of the baffle 22.

[0027] Specifically, the distance between the axis of the corner limiting post 231 and the inner top wall of the dust cover 20 is greater than the distance between the rotation axis of the limiting hook 221 and the top edge of the baffle 22, so that when the baffle 22 rotates around the axis of the corner limiting hook 221, the upper edge of the baffle 22 will not collide with the top wall of the dust cover 20, and the normal rotation of the baffle 22 will not be affected.

[0028] Furthermore, a bearing 232 is sleeved on the corner limiting post 231, or a roller with a similar function to the bearing 232 can also be provided. The bearing 232 is connected to the limiting hook 221. Specifically, the limiting hook 221 is "J" shaped, including a straight handle 2211 and a semi-circular hook 2212. The handle 2211 is connected to the baffle 22, and the hook 2212 is connected to the bearing 232. By providing the bearing 232, the smoothness of the rotation of the baffle 22 can be improved, the mutual wear between the corner limiting post 231 and the limiting hook 221 can be reduced, and the service life of the parts can be extended.

[0029] Specifically, the slitting machine body 10 includes a main pressure roller 12 and a secondary pressure roller 13 arranged parallel to each other below the feed inlet 11. The main pressure roller 12 and the secondary pressure roller 13 rotate in opposite directions. The gap between the main pressure roller 12 and the secondary pressure roller 13 is directly opposite to the center of the feed inlet 11, allowing the rubber material to be drawn into the gap more quickly for extrusion. After passing through the gap, the rubber material is extruded into a sheet shape. A cutting blade assembly 14 is arranged below the main pressure roller 12. Lifting cylinders 15 are connected to both ends of the cutting blade assembly 14. The air cylinder 15 is used to drive the cutting blade assembly 14 closer to or further away from the main pressure roller 12, so as to facilitate the adjustment of the cutting of the strip. After the sheet-like rubber material is clamped and cut by the main pressure roller 12 and the cutting blade assembly 14, it becomes several strips. A conveyor belt 16 is set below the main pressure roller 12. The conveyor belt 16 is located outside the main pressure roller 12. After the rubber strip is cut out, it is manually pulled onto the conveyor belt 16. The rotation direction of the conveyor belt 16 is opposite to the rotation direction of the main pressure roller 12, which can continuously transport the strip.
