Description

Technical Field

[0001] The utility model relates to the technical field of rubber sleeve molding of printer rubber rollers, in particular to a post-extrusion turnover structure of a rubber sleeve extruder. Background Art

[0002] The printer rubber roller consists of a core rod and a rubber sleeve wrapped around the outside of the core rod. The rubber sleeve is extruded by an extruder. In the past, when the rubber sleeve was extruded by the extruder, the core rod was directly inserted from one side. For later processing, it was necessary to use tape to bundle the core rod after it was inserted. Moreover, since the length of the core rod is set, the rubber sleeve needs to be cut at equal distances at the same time. The above-mentioned multiple operations cannot be completed by the machine and need to be operated manually. Now, in order to save manpower and improve efficiency, the rubber sleeve is formed at one time and then The long-distance equidistant cutting is then carried to the next process for re-cutting and inserting the core rod. This new process adds a rubber sleeve initial cutting and swing plate structure at the end of the extruder. The cut rubber sleeve is placed on a pallet, and the pallet carrying the rubber sleeve is transported to the rod insertion equipment through a trolley frame. The pallet carrying the rubber sleeve is then taken out of the trolley frame and placed on the cutting platform of the rod insertion equipment. At the same time, the rubber sleeves need to be placed one by one on the cutting platform. This turnover process is more troublesome and time-consuming, affecting efficiency.

[0003] Therefore, in order to correct the above-mentioned defect, we propose a rubber sleeve extruder post-extrusion turnover structure. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a technical solution:

[0022] See also Figure 1-6 , a turnover structure for a rubber sleeve extruder after extrusion, which includes a trolley 1 and a frame 2 installed on the trolley 1. L-shaped support bars 3 are equidistantly provided on both sides of the interior of the frame 2. Rubber sleeve trays 4 are placed on the two L-shaped support bars 3 on the same straight line. The rubber sleeve tray 4 can be taken out from the frame 2 and then placed on the cutting equipment of the extruder for material connection. The upper end surface of the rubber sleeve tray 4 is equidistantly provided with rubber sleeve receiving grooves 9, each of which accommodates a rubber sleeve. The frame 2 is composed of four vertical poles, and the rubber sleeve receiving grooves 9 on both sides of the upper end surface of the rubber sleeve tray 4 are between the two vertical poles. When the pallet is transported to the cutting platform of the rod threading equipment by the trolley 1, the opening of the rubber sleeve receiving groove 9 is facing the cutting platform, and the worker can directly pull the rubber sleeve on the pallet to the cutting platform without taking the pallet out of the frame 2.

[0023] In the above, in order to make the rubber sleeve tray 4 lighter, the rubber sleeve tray 4 is made into a hollow structure, and the two sides of the rubber sleeve tray 4 corresponding to the two openings of the rubber sleeve accommodating groove 9 are cylindrical, that is, the two sides of the rubber sleeve accommodating groove 9 are relatively convex. When the pallet is higher than or lower than the cutting platform, the rubber sleeve is pulled, and the rubber sleeve contacts the convexity of the pallet where it is located or the convexity of the pallet above, and the contact surface is arc-shaped, which can reduce resistance and wear.

[0024] Furthermore, the above shows that when the pallet is higher than or lower than the cutting platform, the rubber sleeve is pulled and contacts the protrusion of the pallet on which it is located or the protrusion of the pallet above. In order to further reduce resistance and wear, an opening is provided at the lower end of the cylindrical end of the rubber sleeve pallet 4, and a roller shaft 7 is installed inside the cylindrical end of the rubber sleeve pallet 4. Both ends of the roller shaft 7 are connected to the cylindrical end through bearings 8, and a round roller 6 is sleeved on the outside of the roller shaft 7. The round roller 6 protrudes from the opening, and a receiving groove 10 is provided at the upper end of the cylindrical end of the rubber sleeve pallet 4. The round roller 6 protrudes from the receiving groove 10, and the depth of the receiving groove 10 is greater than the height of the cylindrical end.

[0025] That is, the friction between the rubber sleeve and the raised part changes from sliding to rolling friction, so that during traction, the resistance will be smaller and the sleeve will enter the cutting platform more smoothly.

[0026] In addition, the heights of the two sides of the rubber sleeve tray 4 corresponding to the two openings of the rubber sleeve accommodating groove 9 are greater than the height of the rubber sleeve tray 4, and the depth and width of the rubber sleeve accommodating groove 9 are both greater than the diameter of the rubber sleeve, which can better limit the rubber sleeve and prevent it from being scattered on the tray.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
