Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a tube sealing heat sealing machine. Background Technology

[0002] A tube sealing heat sealer is a device used to heat seal tubular objects, mainly for sealing materials such as blood bags and plastic tubes.

[0003] Utility model patent CN213618397U discloses a portable tube sealing heat sealing machine, specifically including a heat sealing machine body. The top of the heat sealing machine body includes a box, a placement groove, and a pipe. The bottom of the heat sealing machine body includes a battery and a fixing base. The exterior of the heat sealing machine body includes a control device and a sealing device. The control device includes a thermal switch, a closing switch, and a button. The sealing device includes an upper block, a lower block, a groove, an upper connecting block, a lower connecting block, a lower fixing block, an upper fixing block, a three-phase motor, a fixing bolt, and a limit strip. This solves the technical problems of existing heat sealing machines being too large and inconvenient to carry, and the plastic tubes having protrusions at the closure point, resulting in a rough and uneven surface.

[0004] However, in existing technologies, core components such as batteries, control devices, and enclosures are often distributed in different locations within the equipment, resulting in uneven overall mass distribution and a mass eccentricity phenomenon. This eccentric layout causes the equipment's center of gravity to deviate from the grip center, requiring additional torque to maintain balance. Prolonged carrying can easily lead to hand fatigue and reduce carrying comfort. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tube sealing heat sealing machine that solves the problem of uneven component layout affecting the carrying capacity of existing equipment.

[0006] To solve the above problems, the technical solution adopted by this utility model is: a tube sealing heat sealing machine, including a heat sealing machine body, a clamping device, a heating device, a control device, a motor, and a storage battery. The heat sealing machine body includes a hollow box. The clamping device is fixedly connected to the central axis inside the hollow box. The heating device is fixedly installed at the end of the clamping device. The control device is located on the top of the box for operating the heating device to start or stop, and controlling the moving blocks to move in opposite directions. The motor is located directly below the symmetrical plane of the bidirectional lead screw, and the rotation of the motor can drive the bidirectional lead screw to rotate. The storage battery is symmetrically arranged on both sides of the bottom of the box.

[0007] Compared with the prior art, the beneficial effects of the scheme are: by fixing the clamping device on the central axis inside the hollow box body, the motor is centrally arranged below the symmetric part of the bidirectional screw rod, and the storage battery is symmetrically distributed on the two sides of the bottom of the box body, the core components are arranged along the central axis or the symmetric axis, the overall mass distribution of the equipment is effectively balanced, and the problem of inconvenience caused by mass eccentricity is avoided.

[0008] Further, the heat sealing machine body further comprises a handle centrally arranged on the upper part of the box body and four fixed bottom columns symmetrically arranged on the lower part of the box body. The handle is located at the geometric center of the upper part of the box body and matches the mass distribution of the symmetric layout of the equipment; when the equipment is lifted, the center of gravity is vertically aligned with the handle, and it is more labor-saving to hold it with one hand, thereby avoiding the shaking or tilting of the equipment during carrying caused by the offset of the center of gravity; the fixed bottom columns form a stable support surface and uniformly transmit the weight of the equipment to the ground.

[0009] Further, the clamping device comprises a fixed groove, a bidirectional screw rod and a moving block. The fixed groove is in the shape of an arc-shaped groove and is fixedly connected to the central axis of the box body. Two moving blocks are symmetrically arranged on the two sides of the fixed groove. Two bidirectional screw rods are arranged on the two sides of the bottom end face of the moving block. The bidirectional screw rods are symmetrically arranged perpendicularly to the clamping device and are connected to the box body at both ends and can rotate around the axis. The number of moving blocks is two, which are symmetrically arranged on the bidirectional screw rods and can move along the bidirectional screw rods. When moving towards each other, the pipe to be heat sealed is fixed by the limiting groove. By fixing the pipe to be heat sealed by the clamping device, the problems of uneven sealing and tight sealing caused by the movement or offset of the pipe during heating are avoided.

[0010] Further, the moving block comprises a block body, a limiting groove fixedly connected to the block body in the opposite direction, and a front moving circular column and a rear moving circular column fixedly connected to the front and rear ends of the block body, respectively. By the cooperation of the limiting groove and the block body, the minimum or maximum opening distance of the moving block can be set to prevent excessive clamping from causing pipe collapse or insufficient clamping from causing tight sealing.

[0011] Further, the heating device comprises a fixed block and a heat sealing block. The heating device is fixedly installed at the end of the clamping device. The fixed block is connected to the heat sealing block through a crank slider mechanism. The fixed block is fixedly connected to the two sides of the fixed groove. The heat sealing block can be heated and moved towards each other with the central axis as the symmetric center. The fixed block is provided with a crank for circular motion, and the heat sealing block is equivalent to a slider for linear motion. When the heat sealing block moves towards each other, heat is symmetrically transferred from the two sides of the pipe, so that the material at the sealing position is in a molten state, and the surface is smooth without burrs.

[0012] Further, the control device comprises a thermal switch, a closing switch and an adjusting switch; the thermal switch is separately arranged on one side of the top of the box body and is used to start or stop the heating device; the closing switch and the adjusting switch are arranged on the other side of the top of the box body; the closing switch is used to control the start or stop of the motor and further control the rotation of the bidirectional screw rod so as to drive the movement of the moving block; the adjusting switch is used to control the rotation direction of the motor and further control the rotation direction of the bidirectional screw rod so as to control the opposite movement or the back movement of the moving block. The thermal switch is separately arranged on one side of the top of the box body, so that the operator can quickly and intuitively start or stop the heating device; the closing switch and the adjusting switch are arranged on the other side of the top of the box body, so that the operator can comprehensively control the rotation direction of the motor and the bidirectional screw rod through a single position.

[0013] Further, one end of the motor is connected with a bevel gear, and another bevel gear is fixedly connected with the central axis of the bidirectional screw rod; the axes of the two bevel gears are arranged perpendicularly to each other, so that the rotation direction can be changed from horizontal to vertical; when the two bevel gears are engaged, the rotation power is transmitted along a right angle, the rotation plane is changed, and the rotation of the motor can drive the rotation of the bidirectional screw rod. Through the engagement of the two-axis perpendicular bevel gears, the horizontal rotation power of the motor can be changed into the vertical rotation power of the bidirectional screw rod, the rotation plane is changed at a right angle, the layout limitation problem caused by the installation direction conflict between the motor and the bidirectional screw rod is solved, the overall structure of the equipment is more compact, and the application scene in a narrow space is adapted.
