Description

Telescopic finger for knife grinder
Technical Field
The invention relates to the field of cutting equipment, in particular to a telescopic finger part of a knife grinding device for a soft material cutting device.
Background
The automatic cutting machine is used for cutting and cutting sheets in various industries, can cut rapidly according to the received design drawings, and has high automation program; the operation is simple. Is cutting equipment adopted in many industries at present. When the cutting machine is used for cutting, the cutter needs to sharpen the cutter at regular time or irregular time so as to ensure the stable cutting capability of the cutter. CN202020689666.3 discloses a knife sharpening device, but when the device is in operation, the abrasion-resistant piece on the telescopic finger falls off during the knife sharpening process, which is a significant problem affecting the sharpening effect.
Disclosure of Invention
The technical problems to be solved by the invention are as follows: the problem of wear pad on the flexible finger drops at the in-process of whetting a knife is solved.
The invention provides the following technical scheme: the utility model provides a knife sharpening device is with flexible finger, includes pars contractilis and fixed part, pars contractilis one end pass through elastomeric element and connect the one end at the fixed part, pars contractilis fixed with the fixed plate in the position that the cut-off knife corresponds, the fixed plate surface be equipped with the recess, the recess is inside to be fixed with the wear pad that the size corresponds.
Furthermore, the wear-resistant piece is a tungsten steel piece, and the edge angle of the wear-resistant piece parallel to the fixed part is a chamfer or a circle.
Further, the wear-resistant plate is fixed with the fixing plate through glue.
Further, the glue is prepared by combining the following raw materials in parts by weight: 10-30 parts of polypropylene glycol, 10-30 parts of polyvinyl alcohol, 5-10 parts of formaldehyde, 3-5 parts of urea, 3-5 parts of polyester resin, 1-3 parts of stabilizer, 1-3 parts of anti-aging agent and 1-3 parts of plasticizer.
Further, the glue is prepared by combining the following raw materials in parts by weight: 25 parts of polypropylene glycol, 15 parts of polyvinyl alcohol, 10 parts of formaldehyde, 5 parts of urea, 5 parts of polyester resin, 1.5 parts of stabilizer, 1.5 parts of anti-aging agent and 1.5 parts of plasticizer.
The invention has the beneficial effects that: with flexible finger institutional advancement, adopt embedded formula design, wear pad side and bottom surface all can laminate with the fixed plate to guarantee the fastness of wear pad. The high-performance glue is strong in adhesive force, cannot corrode a machine, and can ensure that the wear-resistant sheet is more firmly adhered.
Drawings
Fig. 1 is a schematic structural view of a knife grinder.
Fig. 2 is an enlarged view of a partial structure of the retractable finger.
Detailed Description
As shown in fig. 1, the knife sharpening device comprises a telescopic finger, a driving device 5 and a driving wheel 6, one end of the telescopic finger is fixed to the side wall of a connecting arm 8, the driving device 5 is installed on the upper end face of the connecting arm 8, the output end of the driving device 5 is connected with the driving wheel 6, the other end of the telescopic finger 1 is provided with a driven wheel 7 capable of freely rotating, and a knife sharpening abrasive belt is wound between the driving wheel 6 and the driven wheel 7. When sharpening is needed, the driving device 5 drives the driving wheel 6 to rotate, and then the sharpening abrasive belt rotates between the driven wheel 7 and the driving wheel 6.
As shown in fig. 2, the telescopic finger includes a telescopic portion 1 and a fixing portion 4, one end of the telescopic portion 1 is connected to one end of the fixing portion 4 through an elastic component, the other end of the fixing portion is fixed to a side wall of a connecting arm 8, the other end of the telescopic portion is provided with a driven wheel 7, the telescopic portion 1 is fixed with a fixing plate 2 at a position corresponding to the cutting knife, a groove is formed in the surface of the fixing plate 2, and a wear-resistant piece 3 corresponding to the size is fixed inside the groove. The wear-resistant plate 3 is fixed with the fixed plate 2 through glue. The cutter sharpens the knife by contacting with the sharpening abrasive belt at the position of the wear-resistant sheet 3, thereby effectively improving the sharpening effect and protecting the telescopic part 1. The wear-resistant plate 3 is preferably a tungsten steel plate, and the corner of the wear-resistant plate 3 parallel to the fixed part 4 is a chamfer or a fillet. The edge angle of the wear-resistant piece is set to be the chamfer angle and the fillet angle, so that the damage of the sharpening abrasive belt caused by the friction between the sharpening abrasive belt and the edge angle of the wear-resistant piece in the rotation process of the sharpening abrasive belt can be effectively avoided.
The invention further provides glue for fixing the wear-resistant sheet, which is prepared from the following raw materials in parts by weight: 10-30 parts of polypropylene glycol, 10-30 parts of polyvinyl alcohol, 5-10 parts of formaldehyde, 3-5 parts of urea, 3-5 parts of polyester resin, 1-3 parts of stabilizer, 1-3 parts of anti-aging agent and 1-3 parts of plasticizer.
The glue is prepared from the following raw materials in parts by weight: 25 parts of polypropylene glycol, 15 parts of polyvinyl alcohol, 10 parts of formaldehyde, 5 parts of urea, 5 parts of polyester resin, 1.5 parts of stabilizer, 1.5 parts of anti-aging agent and 1.5 parts of plasticizer. The embodiment is a preferable mode, and the glue has the best bonding effect at this time, so that the wear-resistant sheet 3 and the fixed plate 2 can be bonded to the maximum extent.
