Description

Technical Field

[0001] The utility model belongs to the technical field of rubber strip processing, and in particular relates to a rubber strip uniform cutting device. Background Art

[0002] The production process of rubber strips is generally as follows: 1. Rubber refining: The mixed rubber raw materials are added to the rubber compound in the rubber mixer according to the formula requirements, and then the rubber compound is pressed into rubber compound after continuous mixing. 2. Extrusion: Install a mouth mold on the head of the extruder, put the refined rubber compound into the automatic feeder, let the rubber compound naturally enter the extruder barrel from the feeding device, and then move the rubber compound toward the die head through the rotation of the screw to extrude the shape of the sealing strip. 3. Vulcanization: The extruded sealing strip enters the drying tunnel for high-temperature vulcanization and characterization. Some products will be placed in the oven for secondary heating and shaping. 4. Subsequent processing: Cut or bond according to the length required by the customer, and then package and ship to the customer as required.

[0003] In the production and processing of rubber strips, the rubber strips need to be initially cut and then placed in an extruder. Since the feed port of the extruder is small, most of the existing technologies cut the rubber strips manually by workers. During cutting, the width of the rubber strips may be different. Therefore, when placing the rubber strips in the extruder, the feed port of the extruder may be blocked, thereby affecting production efficiency. For this reason, we propose a rubber strip uniform cutting device to solve the above-mentioned problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 The utility model provides a rubber strip uniform cutting device, comprising a support component 1, a moving component 2 and a cutting component 3 arranged on the support component 1, and a pushing component 4 arranged on the moving component 2;

[0027] Among them, the cutting assembly 3 includes a cutting seat 31, a bevel tooth plate 33, a cutting knife 34, an A bevel gear 35, a B bevel gear 36 and a linkage rod 37. The cutting seat 31 is fixedly connected to the upper end of the support assembly 1. Two limiting grooves are provided on the cutting seat 31. Two bevel tooth plates 33 are provided. Both bevel tooth plates 33 are slidably connected in the limiting grooves. Two cutting knives 34 are provided. Both cutting knives 34 are fixedly connected to the lower ends of the bevel tooth plates 33. Both A bevel gear 35 and B bevel gear 36 are provided above the cutting seat 31. The linkage rod 37 is fixedly connected between the A bevel gear 35 and the B bevel gear 36. Both the A bevel gear 35 and the B bevel gear 36 are meshed with the two bevel tooth plates 33.

[0028] Specifically, when cutting the produced rubber strips, in order to make the width of the cut rubber strips consistent, a cutting component 3 can be set on the supporting component 1. The cutting component 3 can be used to cut at a certain frequency, so that the width of the cut rubber strips is consistent. In order to make the rubber strips semi-automatically cut, it is necessary to cooperate with the moving component 2 to operate synchronously during cutting. The moving component 2 can transport the uncut rubber strips and the rubber strips after cutting, so that they can move at a certain speed and cooperate with the cutting of the cutting component 3, so that the width of the cut rubber strips can be consistent. After the cutting is completed, in order to facilitate the removal of the cut rubber strips, a pushing component 4 is set on the moving component 2. The cut rubber strips can be pushed out by the pushing component 4, so that the rubber strips can be collected easily.

[0029] Furthermore, when the rubber strip is cut, it can be achieved by rotating the B bevel gear 36. Since the B bevel gear 36 and the A bevel gear 35 are fixedly connected by the linkage rod 37, when the B bevel gear 36 rotates, the A bevel gear 35 will be driven to rotate together, and since the A bevel gear 35 and the B bevel gear 36 are both meshed with the two bevel gear plates 33, when the B bevel gear 36 and the A bevel gear 35 rotate, the two bevel gear plates 33 will be driven to move up and down, and a cutting knife 34 is fixedly connected to the lower end of the bevel gear plate 33. At this time, the rubber strip can be cut by the cutting knife 34. In order to improve the cutting efficiency, two bevel gear plates 33 and two cutting knives 34 are provided. When the A bevel gear 35 and the B bevel gear 36 rotate, one group of bevel gear plates 33 and the cutting knife 34 will be driven to rise, and the other group of bevel gear plates 33 and the cutting knife 34 will be driven to fall, and quick cutting can be performed at this time.

The specific operation is as follows:

[0033] B motor 32: First, make sure you are using a bidirectionally rotatable B motor 32. This B motor 32 is usually provided with two output terminals and allows current to flow in both directions, thereby changing the direction of rotation.

[0034] Relays: Two relays are required, one for each direction of the motor. Each relay has a normally open contact and a normally closed contact that switch states when the relay is activated.

[0035] Control circuit:

[0036] Power supply: Provide power to the B motor 32 and the relay. Make sure the power supply can handle the current demand of the B motor 32.

[0037] Switch: Use a switch such as a push button or timer to control the activation of a relay.

[0038] Logic Circuit: The activation sequence and timing of the relays can be programmed using logic gates like AND gate or OR gate or a microcontroller.

[0039] set up:

[0040] Relay 1: Set up Relay 1 so that its normally open contacts are connected to one output of the motor when activated, and its normally closed contacts are connected to the return path of the other output.

[0041] Relay 2: For Relay 2, set its normally open contact to connect to the other output terminal of the motor when activated, and its normally closed contact to connect to the return path of the first output terminal.

[0042] Control Logic: Programming logic circuits or microcontrollers to cause the relays to activate in a predetermined sequence and time intervals. For example, relay 1 can be set to activate for a period of time, then relay 2 to activate for a period of time, then relay 1 to activate again, and so on.

[0043] Safety measures: Make sure the entire system has overload protection and short-circuit protection to prevent damage to the motor or relay.

[0044] In this embodiment, the support assembly 1 includes a support plate 11 and support legs 12 . The support legs 12 are disposed at the lower end of the support plate 11 , and a movable groove is formed on the surface of the support plate 11 .
