Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber sealing strip processing, in particular to a silicone rubber sealing strip deburring device. Background Art

[0002] Silicone rubber sealing strips are widely used in the fields of automobiles, construction, electronics, electrical appliances, etc., mainly for sealing and protection. They have excellent heat resistance, cold resistance, ozone resistance and aging resistance.

[0003] In the prior art, such as Chinese Patent CN 214082416 U, a deburring device for rubber parts is disclosed. The device includes a workbench with a ball bearing movably mounted on its top. The device introduces the rubber part into a barrel and activates a stepper motor controlled by a control panel. The stepper motor rotates a turntable via a drive shaft, aligning a first through-hole on the turntable with the barrel. Gravity causes the rubber part to fall into the first through-hole. The turntable then rotates the rubber part to below a tool. The tool control panel controls the extension and retraction of an electric push rod, which in turn moves the tool up and down via a lifting plate to remove the burrs from the rubber part. The burrs fall into a waste bin through a third through-hole. The turntable then rotates the rubber part to a second through-hole, whereupon gravity causes the rubber part to fall into a storage bin through the second through-hole. This achieves a simple and convenient automated processing method. However, this patent still has the following problems.

[0004] In the above patent, although a turntable and a first through hole are provided, when the rubber part in the barrel falls into the first through hole, the turntable rotates to drive the rubber part to move. However, if used for a silicone rubber sealing strip, since the silicone rubber sealing strip is relatively soft, when the turntable rotates, the inner wall of the first through hole will push the silicone rubber sealing strip, which may cause the silicone rubber sealing strip to bulge. When deburring, the blade may cut the wrong position, thereby affecting the quality of deburring. Utility Model Content

[0005] The utility model mainly provides a device for removing burrs of a silicone rubber sealing strip, which is convenient for improving the quality of removing burrs and preventing a blade from cutting at a wrong position.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a silicone rubber sealing strip deburring device, comprising: a base plate, a first through hole and a second through hole are formed through the top of the base plate, a motor is fixedly installed on the bottom of the base plate, the output end of the motor passes through the base plate and is fixedly installed with a turntable, a storage slot is provided on the top of the base plate, an electric telescopic rod is fixedly installed on the bottom of the base plate, the telescopic end of the electric telescopic rod passes through the base plate into the storage slot and is fixedly installed with a slide, four evenly distributed third through holes are formed through the top of the turntable, a limiting slot is provided on the inner wall of the limiting slot, an electromagnet is fixedly installed on the inner wall of the limiting slot, a first spring is fixedly installed on the outer wall of the electromagnet, a placement plate is fixedly installed on the end of the first spring away from the electromagnet, a slide slot is provided at the bottom of the placement plate, and a pressure sensor is fixedly installed on the inner wall of the slide slot.

[0008] Preferably, a slot is provided at the bottom of the movable plate, a fixed slot is provided on the inner wall of the slot, a second spring is fixedly installed on the inner wall of the fixed slot, a clamping block is fixedly installed on one end of the second spring, a connecting rod is fixedly installed on the end of the clamping block close to the second spring, and the end of the connecting rod away from the clamping block passes through the movable plate and is fixedly installed with a pull plate. When the staff pulls the pull plate, the pull plate drives the clamping block to move through the connecting rod.

[0009] Preferably, a blade is slidably installed inside the slot, and a card slot is provided through the outer wall of the blade. The inner wall of the card slot fits with the outer wall of the card block to prevent the blade from shaking after the card block enters the card slot.

[0010] Preferably, a collection box and a waste box are provided at the bottom of the base plate, for collecting the deburred sealing strip and waste respectively.

[0011] Preferably, support frames are fixedly installed at the four corners of the bottom of the base plate to support the base plate.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the utility model, when in use, the sealing strip falls into the third through hole and falls on the placement plate, and then the motor is started, the turntable rotates, and when cutting, the staff starts the electric telescopic rod, and the telescopic end of the electric telescopic rod pushes the slide plate to leave the storage slot and enter the slide slot. At the end of cutting, the staff starts the electromagnet, and the iron placement plate is attracted and enters the limit slot. At this time, the waste falls into the second through hole from the opening between the placement plate and the inner wall of the third through hole. When the slide plate contacts the pressure sensor, the electromagnet is powered off, and the elastic force of the first spring pushes the placement plate to reset, the telescopic end of the electric telescopic rod retracts, and the slide plate enters the storage slot. When the third through hole moves to above the first through hole, the electromagnet is restarted, and the placement plate completely enters the limit slot. At this time, the sealing strip after deburring enters the first through hole, which can prevent the sealing strip from bulging when moving, thereby improving the quality of deburring.

The card block leaves the card slot and enters the fixed slot. At this time, the blade can be removed from the slot and the top of the new blade is inserted into the slot. The top of the blade contacts the inclined surface of the card block, pushing the card block into the fixed slot. When the card slot moves to the side of the card block, the card block enters the card slot under the elastic force of the second spring, fixes the blade, and facilitates the replacement of the blade.
