Description

Technical Field

[0001] The utility model belongs to the technical field of hot melt adhesive processing and relates to a hot melt adhesive shearing device. Background Art

[0002] Hot melt adhesive is a kind of plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature while its chemical properties remain unchanged. It is non-toxic and odorless, belonging to an environment-friendly chemical product. Because the product itself is solid, it is convenient for packaging, transportation, storage, solvent-free, pollution-free and non-toxic; and because of its simple production process, high added value, large bonding strength and fast speed, etc., it is very popular. Hot melt adhesive is usually extruded into strips by an extruder and is cut simultaneously with a shearing device. However, the existing shearing devices can usually only cut hot melt adhesive rods with the same radius of size. Therefore, it is very necessary to design a hot melt adhesive shearing device. Summary of the Invention

[0003] The purpose of the utility model is to provide a hot melt adhesive shearing device aiming at the above problems existing in the current technology.

[0004] The purpose of the utility model can be realized by the following technical solutions: A hot melt adhesive shearing device, including a frame, is characterized in that a plurality of placement grooves for preventing hot melt adhesive rods are arranged at the front end of the frame, a pushing mechanism for pushing the hot melt adhesive rods is arranged at the bottom of the placement grooves, and a cutting mechanism for cutting the hot melt adhesive rods is arranged at the end of the placement grooves, including a first mounting frame which is mounted on the frame. A through groove for the hot melt adhesive rod to pass through is arranged on the first mounting frame, a guide groove is arranged in the through groove, and a laser cutting device is slidably mounted in the guide groove through a driving member. A positioning mechanism for assisting in fixing during the cutting of the hot melt adhesive rod is arranged above the cutting mechanism, including a second mounting frame. A push rod motor is vertically mounted on the top of the second mounting frame, a mounting member is mounted on the rod portion of the push rod motor, and a plurality of fixing strips with an arc-shaped cross section are mounted on the mounting member. A control console for controlling each mechanism is arranged on the side of the frame.

[0005] The working principle of the utility model is as follows: Place the hot melt adhesive rods to be cut in the placement grooves (hot melt adhesive rods with different radii of size and lengths can be placed simultaneously or in batches). First, control the pushing mechanism through the control console to make the cutting end of the hot melt adhesive rod located below the laser cutting device. Then, after setting the cutting size through the control console, cut the hot melt adhesive rod with the laser cutting device, and at the same time, the pushing mechanism synchronously pushes the hot melt adhesive rod to realize the cutting process.

[0006] The propulsion mechanism includes a first drive roller, a second drive roller, a drive belt, a pusher, and a drive motor. The first drive roller and the second drive roller are respectively installed on the frame below both ends of the placement groove. A drive belt is correspondingly arranged below each placement groove and sleeved between the first drive roller and the second drive roller. A pusher is installed on the drive belt. A sliding groove for the pusher to slide is opened at the bottom of the placement groove. The drive motor is installed inside the frame, and the output end of the drive motor is connected to the end of the second drive roller through a synchronous belt pulley structure.

[0007] With the above structure, by controlling the rotation of the second drive roller with the drive motor, the pusher is driven to move horizontally in the placement groove under the action of the drive belt and the second drive roller, thereby pushing the hot melt adhesive stick to move.

[0008] The cutting mechanism is rotatably installed on the frame through a rotating member.

[0009] With the above structure, when not in use, the cutting mechanism is retracted, which is convenient for putting the hot melt adhesive stick into the placement groove. At the same time, it is convenient for the disassembly and assembly of the laser cutting device when it is turned down.

[0010] The center lines of the placement groove and the fixing strip correspond to each other.

[0011] With the above structure, it can position hot melt adhesive sticks with various different size radii.

[0012] Side plates are installed on the side of the frame.

[0013] With the above structure, it is convenient for the disassembly and assembly inside the frame.

[0014] Compared with the prior art, this hot melt adhesive shearing device has the following advantages: By setting a number of placement grooves and the positioning mechanism matching therewith, cooperating with the laser cutting device and the propulsion mechanism, while ensuring the cutting effect, it can well cut hot melt adhesive sticks with different size radii and lengths within a certain range.
