Abstract
The utility model discloses a kind of food processing seal with good abrasion resistance, including sealing lip, skeleton, self-lubricating abrasion-resistant patch；The position of sealing lip and the cooperation of self-lubricating abrasion-resistant patch is lip, and the lip position is provided with patch and places annular groove, above-mentioned self-lubricating abrasion-resistant patch setting is placed in annular groove in the patch；Skeleton has towards lip direction reinforces end, which has a reinforcement step.The utility model can solve how to reduce the technical issues of abrasion and fever of lip and cutter shaft.
Description
Technical field
The utility model relates to a kind of food processor suitable for using inside 45000 turns of food processor below
Sealing element, matching to merge with cutter shaft has good wearability.
Background technique
Referring to FIG. 1, the lip of existing food processing seal thereon is formed using vulcanizable fluororubber, such as magnitude of interference mistake
Greatly, the abrasion and fever of lip and cutter shaft will significantly increase, to cause to wear and leak, usually lip is to use at present
The amount of being full of 0.5mm, the design of thickness 0.6mm.
Utility model content
The purpose of the utility model is to provide a kind of food processing seal with good abrasion resistance, solve how
The abrasion and fever for reducing lip and cutter shaft, thus the technical issues of improving sealing reliability.
Food processing seal with good abrasion resistance, including sealing lip, skeleton, self-lubricating abrasion-resistant patch；
The position of sealing lip and the cooperation of self-lubricating abrasion-resistant patch is lip, and the lip position is provided with patch and places annular groove, above-mentioned
The setting of self-lubricating abrasion-resistant patch is placed in annular groove in the patch；Skeleton has towards lip direction reinforces end, which has
One reinforcement step.
The self-lubricating abrasion-resistant patch is polytetrafluoroethylene (PTFE) patch.
The polytetrafluoroethylene (PTFE) patch is placed on annular groove by the patch that sulfidization molding is pasted onto lip.
The self-lubricating abrasion-resistant patch with a thickness of 0.3-0.5mm, lip and self-lubricating abrasion-resistant patch it is whole thick
Degree is 0.8-1.0mm.
53 ° -57 ° of the upper labial angle of the lip, 21 ° -25 ° of lower labial angle.
The height for reinforcing step is 0.5-.0.8mm.
The skeleton internal diameter of the skeleton and the lip root spacing of lip are 0.5-0.7mm.
It is formed the beneficial effects of the utility model are: the utility model removes a part of material in original lip position first
Patch places annular groove, is then bonded polytetrafluoroethylene (PTFE) patch on fluorubber lip in sulfidization molding, and polytetrafluoroethylene (PTFE) patch is thick
0.3-0.5mm is spent, lip thickness is optimized to lip and patch integral thickness 0.8-1.0mm by 0.6mm, 53 ° -57 ° of upper labial angle, under
21 ° -25 ° of labial angle, optimize by above-mentioned design, after magnitude of interference is increased to 0.7-1.0mm. raising lip thickness and magnitude of interference, increases
Add oil seal lip to the radial force of cutter shaft, but because the self-lubrication and wearability for utilizing polytetrafluoroethylene material excellent, lip
Smaller than before improving to the friction torque of cutter shaft, the abrasion of lip is lower than before improving after work, to improve sealing reliability.Cause
Polytetrafluoroethylene (PTFE) resilience is poor, and polytetrafluoroethylene (PTFE) patch is bonded directly on original structure, and when assembling cutter shaft, lip can be turned down, and lead
Cause seal failure.For solve lip fold, support frame by the basis of inverted L shape increase by a 0.5 mm height step, that is, skeleton
Reinforce end, and skeleton internal diameter and lip root spacing are 0.5-0.7mm.
Detailed description of the invention
Fig. 1 is the schematic diagram of existing sealing element；
Fig. 2 is the schematic diagram of the sealing element in embodiment；
1. sealing lips, 11. lips, 111. patches place annular groove, 112. lip roots, 2. skeletons, 21. in figure
Reinforce end, 211. reinforcement steps, 22. skeleton internal diameters, 3. self-lubricating abrasion-resistant patches.
Specific embodiment
Referring to FIG. 2, the food processing seal with good abrasion resistance in figure, including a sealing lip 1, one
2, self-lubricating abrasion-resistant patches 3 of a skeleton.
Sealing lip 1 is vulcanized using fluorubber material, and the position that sealing lip 1 cooperates with self-lubricating abrasion-resistant patch 3 is
Lip 11, carried out on the basis of 11 position of lip is in former lip design of material formed patch place annular groove 111, it is above-mentioned from
Lubricating and wear-resisting patch 3 is pasted onto the patch by sulfidization molding and places in annular groove 111.The self-lubricating abrasion-resistant patch 3 is poly-
Tetrafluoroethene patch, with a thickness of 0.3-0.5mm, the integral thickness of lip 11 and self-lubricating abrasion-resistant patch 3 is 0.8-1.0mm.
53 ° -57 ° of the upper labial angle of the lip 11,21 ° -25 ° of lower labial angle.Optimize by above-mentioned design, magnitude of interference is increased to 0.7-1.0mm.
After improving lip integral thickness and magnitude of interference, increase oil seal lip 1 to the radial force of cutter shaft, to improve sealing reliability.
If do not optimized to green bone frame after above-mentioned self-lubricating abrasion-resistant patch 3 is pasted, in assembling knife
When axis, lip 11 can be turned down, and lead to seal failure.For solve lip 11 turn down, skeleton 2 by the basis of former inverted L shape towards 1 side of lip
To a reinforcement end 21 is increased, which has the reinforcement step 211 of a 0.5-0.8mm height, and skeleton internal diameter 22
It is 0.5-0.7mm with 112 spacing of lip root.
