Description

Technical Field

[0001] This utility model belongs to the field of capillary copper tube technology, and in particular relates to a capillary copper tube packaging machine. Background Technology

[0002] Copper and copper alloy capillary tubes, also known as pure copper capillary tubes, are seamless tubes produced by pressing and drawing. They are strong, corrosion-resistant, lightweight, have good thermal conductivity, and high low-temperature strength. They are commonly used in the manufacture of heat exchange equipment (such as condensers). They are also used in oxygen production equipment for assembling cryogenic pipelines. Small-diameter copper capillary tubes are often used to transport pressurized liquids (such as in cooling systems, lubrication systems, and hydraulic systems) and as pressure measuring tubes in instruments.

[0003] After the capillary copper tubes are processed, they need to be packaged in batches using plastic bags. The current packaging process is done manually, which is inefficient. Utility Model Content

[0004] In view of this, the present invention provides a capillary copper tube packaging machine to realize the automation of capillary copper tube packaging.

[0005] To solve the above technical problems, the technical solution of this utility model is to use a capillary copper tube packaging machine, which includes a front conveyor belt, a middle conveyor belt and a rear conveyor belt arranged in sequence for conveying capillary copper tubes, an alignment mechanism installed on the front conveyor belt for aligning the capillary copper tubes to be packaged, a sealing mechanism installed on the middle conveyor belt for closing and sealing the two sides of the belt, and a cutting mechanism installed on the rear conveyor belt for cutting the sealed belt.

[0006] The sealing mechanism includes side panels on both sides of the front end of the middle section conveyor belt, which fold the edges of the belt material passing between the front and middle sections towards the middle; it also includes sealing irons arranged behind the side panels, which are two irons arranged in a left-right direction, so that the edges of the belt material are heated and bonded together when passing through the gap between the two sealing irons.

[0007] As an improvement, a pair of guide wheels is provided at the front and / or rear of the sealing soldering iron.

[0008] As a further improvement, the sealing soldering iron is rectangular and uses a resistance wire for heating; the distance between the two sealing soldering irons is adjustable.

[0009] As another further improvement, the guardrail is a right-angled triangle with one right-angled side fixed to the frame of the middle conveyor belt and the tip pointing towards the front end of the middle conveyor belt.

[0010] As an improvement, the feed rollers that wind up the strip are positioned below the middle section of the conveyor belt.

[0011] As an improvement, the alignment mechanism includes a gantry frame fixed on the front conveyor belt frame, and a flap that is movably connected to the gantry frame; the flap switches between a working position and an open position. When the flap is in the working position, it can prevent the capillary copper tubes on the front conveyor belt from moving with the front conveyor belt; when the flap is in the open position, it eliminates the obstruction to the capillary copper tubes.

[0012] As an improvement, the upper end of the flap is rotatably connected to the gantry via a rotating shaft; when the flap rotates to the working position, it is perpendicular to the front conveyor belt and the gap between it and the front conveyor belt is smaller than the diameter of the capillary copper tube; when the flap rotates to the open position, a gap is left between it and the front conveyor belt for the capillary copper tube to pass through.

[0013] As an improvement, the rear conveyor belt is annular and has a perforation, and also includes two cutters arranged opposite each other in the vertical direction; the two cutters can rotate synchronously in opposite directions, and when they rotate to face each other, the blades are exactly at the perforation of the rear conveyor belt, thereby cutting the sealed belt material.

[0014] As an improvement, the cutouts on the rear conveyor belt are arranged at equal intervals along its axis.

[0015] As an improvement, a brush roller is provided behind the cut strip, and the brush roller rotates from front to back, which can separate the cut strip from the uncut strip behind it.

[0016] The advantages of this utility model are:

[0017] The capillary copper tube packaging machine with the above structure aligns the capillary copper tubes to be packaged using an alignment mechanism installed on the front conveyor belt, then seals the two sides of the strip using a sealing mechanism installed on the middle conveyor belt, and finally cuts the sealed strip using a cutting mechanism installed on the rear conveyor belt. The entire process requires no manual intervention, automating the packaging process and greatly improving the efficiency and quality of packaging. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1 As shown, this utility model provides a capillary copper tube packaging machine, including a front conveyor belt 1, a middle conveyor belt 2, and a rear conveyor belt 3 arranged in sequence for conveying capillary copper tubes, an alignment mechanism installed on the front conveyor belt 1 for aligning the capillary copper tubes to be packaged, a sealing mechanism installed on the middle conveyor belt 2 for closing and sealing the two sides of the belt, and a cutting mechanism installed on the rear conveyor belt 3 for cutting the sealed belt.

[0025] Specifically, such as Figure 2 As shown, the alignment mechanism includes a gantry frame 4 fixed on the frame of the front conveyor belt 1, and a flap 5 movably connected to the gantry frame 4; the flap 5 switches between a working position and an open position. When the flap 5 is in the working position, it can prevent the capillary copper tube on the front conveyor belt 1 from moving with the front conveyor belt 1; when the flap 5 is in the open position, it eliminates the obstruction to the capillary copper tube.

[0026] More specifically, the upper end of the flap 5 is rotatably connected to the gantry 4 via a rotating shaft; when the flap 5 is rotated to the working position, it is perpendicular to the front conveyor belt 1 and the gap between it and the front conveyor belt 1 is smaller than the diameter of the capillary copper tube; when the flap 5 is rotated to the open position, a gap is left between it and the front conveyor belt 1 for the capillary copper tube to pass through.

[0027] The capillary copper tubes, initially stacked on the front conveyor belt 1 according to their individual package quantities, are not aligned. When they reach the alignment device, the flap 5 blocks them from the alignment position. As the front conveyor belt 1 continues to move, the capillary copper tubes, which were originally misaligned in the front-to-back direction, are aligned by the flap 5. After alignment, the flap 5 flips up to an angle of over 45° to the open position, creating a gap for the aligned capillary copper tubes to pass through. Before the next stack of capillary copper tubes arrives, the flap 5 flips down to the working position, and the cycle repeats.

[0028] like Figure 3As shown, the sealing mechanism includes side panels 7 on both sides of the front end of the middle conveyor belt 2, which fold the edges of the belt material passing between the front conveyor belt 1 and the middle conveyor belt 2 towards the middle; it also includes sealing irons 9 behind the side panels 7, which are two pieces arranged in the left and right direction, so that the edges of the belt material are heated and bonded together when passing through the gap between the two sealing irons 9.

[0029] More specifically, guide wheels 8 are provided in front of and / or behind the sealing soldering iron 9. The rotation of the guide wheels 8 provides forward propulsion for the strip. The sealing soldering iron 9 is rectangular and uses resistance wire for heating; the spacing between the two sealing soldering irons 9 is adjustable to accommodate strips of different thicknesses. The guard plate 7 is a right-angled triangle, with one right-angled side fixed to the frame of the middle conveyor belt 2, and the tip pointing towards the front end of the middle conveyor belt 2, so that the sides of the strip passing through the gap between the front conveyor belt 1 and the middle conveyor belt 2 will not be scratched by the guard plate 7 during the process of folding inward and gradually closing.

[0030] Additionally, for ease of arrangement, the feed roller 6, which winds up the strip, is positioned below the middle conveyor belt 2. After the strip passes through the gap between the front conveyor belt 1 and the middle conveyor belt 2, its two edges converge towards the center under the guidance of the guardrail 7. The guide roller pair 8 clamps the two edges of the strip and provides the power for the strip to move backward by rotating. When the two edges of the strip pass through the sealing iron 9, they melt and bond due to the high temperature, thus forming a seal. The guide roller pair 8, located behind the sealing iron 9, further strengthens the seal.

[0031] When the aligned capillary copper tubes enter the middle section conveyor belt 2, they are located on the belt and sealed in the tubular bag formed by the belt.

[0032] like Figure 4 As shown, the rear conveyor belt 3 is annular and has a cutout 31. It also includes two cutters 10 arranged opposite each other in the vertical direction. The two cutters 10 can rotate synchronously in opposite directions, and when they rotate to face each other, the blades are exactly at the cutout 31 of the rear conveyor belt 3, thereby cutting the sealed belt material.

[0033] The cutouts 31 on the rear conveyor belt 3 are several locations set at equal intervals along its axis, and their specific number is related to the rotational speed of the cutter.

[0034] Each time the two cutting blades 10 rotate until their blades face each other, they can cut the tubular bag formed by the strip material. In some embodiments, the blades of the cutting blades 10 are heated, which actually achieves the cutting by melting the strip material with temperature. However, the melted strip material cools down quickly and can easily re-adhere together. Therefore, a brush roller 11 is provided behind the cutting blades. The brush roller 11 rotates from front to back to separate the cut strip material from the uncut strip material behind it, preventing it from re-adheding to the uncut strip material behind it.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
