Description

elastic roller

The present invention refers to an elastic roller, wherein the elastic roller has an elastic rubber ring, and a first elastic sheet and a second elastic sheet supporting the roller are radiated around the elastic rubber ring in the technical field.

The first press refers to a set of carrier equipment B0 installed on the plastic plate A0. The carrier equipment B0 has a bearing wheel set B01, and the bearing wheel set B01 has a shaft 10 and a spring roller 20 assembled with the shaft 10 above the bearing wheel set B01. The plastic plate A0 (as shown in Figures 1 and 2) is conveyed between the wheel set B01 and the spring roller 20. The spring roller 20 has a first ring body 201 sleeved on the shaft 10. The first ring body A friction ring 30 is sleeved outside 201 , and a second ring body 40 is sleeved around the first ring body 201 for positioning the friction ring 30 with the first ring body 201 . The first ring body 201 is provided with a positioning groove 202 corresponding to the friction ring 30 , and a compression spring 50 limited by the second ring body 40 is placed in the positioning groove 202 . The friction ring 30 is provided with a guide post 301 corresponding to the positioning groove 202 , and the end of the guide post 301 abuts against a spring seat 60 for inserting the compression spring 50 (as shown in FIGS. 3 and 4 ; in addition, the plastic plate A0 is At least include: plastic sheet, composite sheet of plastic and rubber).

The compression spring 50 and the spring seat 60 can just match the thickness of the plastic sheet A0 to squeeze the friction ring 40 . The spring roller 20 is used to cooperate with the friction ring 40 within the moving distance of the friction ring 40 , the spring seat 60 and the compression spring 50 . The carrying wheel set B01 effectively squeezes and transports the plastic sheet A0 (as shown in Figures 1, 2, and 5).

The spring roller 20 selects the compression spring 50 with lower pressure as the differential force and reset source of the friction ring 30, so that the pressure of the compression spring 50 will not damage the plastic plate A0 (as shown in FIG. 5 ) . The pH value and corrosiveness of the gas emitted by the plastic sheet A0 itself are high, which has a strong corrosion effect on the compression spring 50 made of metal, so that the compression spring 50 is damaged and replaced due to corrosion (the plastic Plate A0 as shown in Figures 1, 2 and 5). Then, the user found that the compression spring 50 and the spring seat 60 have the following problems due to disassembly, quantity and assembly (as shown in Figures 3 and 4):

1. If the compression spring 50 and the spring seat 60 are not taken carefully before the spring roller 20 is disassembled, the compression spring 50 and the spring seat 60 will be scattered on the ground after the spring roller 20 is disassembled, and scattered In one place, the compression spring 50 and the spring seat 60 are extremely difficult to clean (as shown in FIGS. 3 and 4 ).

2. The number of the spring roller 20 is too large when the compression spring 50 and the spring seat 60 are assembled, the positioning groove 202 is not easy to accommodate a single compression spring 50, not to mention that the positioning groove 202 is arranged in a ring to accommodate the compression spring 50. It is not easy. In addition, the positioning groove 202 encircling the compression spring 50 causes the problem of high labor cost due to long storage time and high cost of forming a large number of parts (as shown in FIGS. 3 and 4 ).

3. The compression spring 50 is still damaged due to corrosion and must be replaced in a short time. Therefore, it is found that the service life of the compression spring 50 is extremely short (as shown in Figures 3 and 4).

It is concluded that the spring roller 20 has high cost and no practical value (as shown in Figures 3 and 4; in addition, for the detailed information of the spring roller 20 and the compression spring 50, please refer to: "Elastic roller No. M415896" Structure" and "Improved Elastic Roller Structure of No. M595110" shown).

In view of the above, it is known that the conventional spring roller has high cost and lack of practical value. Therefore, the creator of this case is urged to develop in the direction of low cost and high practical value. , according to the design of an elastic rubber ring is the best.

The elastic roller of the present invention has a shaft sleeve, the shaft sleeve is provided with a shaft ring, and one side of the shaft ring protrudes with a wheel ring with an inner diameter. An elastic rubber ring is attached to the wheel ring sleeve. Around the elastic rubber ring, first elastic pieces extending radially and outwardly are distributed annularly at equal distances. The elastic rubber ring is connected to a roller, the inner side of the roller is annularly distributed with inwardly extending rib bodies, there is a radiation chamber for accommodating the first elastic sheet between the rib body and the rib body, and the top edge of the radiation chamber is There is a horizontal sticking portion abutting against the second elastic piece, and the inner bottom side of the rib has an inner end portion, and a first displacement space is maintained between the inner end portion and the elastic rubber ring; and the wheel ring is at least sleeved A limiting ring body is connected, and the elastic rubber ring and the roller are limited between the limiting ring body and the shaft ring.

The ring of the present invention is provided with a concave rubber ring positioning groove, and the inner side of the elastic rubber ring is provided with a rubber ring protrusion embedded in the rubber ring positioning groove; and the inner bottom side of the rib has an inner end portion , a first displacement space is maintained between the inner end and the elastic rubber ring.
