Abstract
Description
Technical Field
[0001] This utility model relates to a packing machine, and more particularly to the core mechanism of the packing machine. Background Technology
[0002] A strapping machine includes a core mechanism, which comprises a heat-bonding mechanism, a sliding mechanism, a top-strap mechanism, and a strap-cutting mechanism. A series of cams mounted on the core shaft are driven by a core motor to control the movement of these mechanisms, thereby securing, cutting, and bonding the strapping. One type of strapping machine uses a strap-reaming mechanism to wrap the strapping around the item. This strap-reaming mechanism also requires power to move around the object while simultaneously moving back and forth relative to it.
[0003] Previously, a single core shaft had to control the movement of all the above mechanisms, resulting in a long core mechanism that was too large in width, taking up a lot of space and having an uncompacted structure. Utility Model Content
[0004] The purpose of this utility model is to provide a core mechanism that makes the core mechanism of a packing machine with a strapping mechanism more reasonable and the structure more compact. To this end, this utility model adopts the following technical solution:
[0005] A mechanism includes a mechanism motor, a mechanism frame, a mechanism shaft, a slide arm and a slide, a heat-adhesive head arm and a heat-adhesive head, a tape handling mechanism, a tape pressing mechanism and a tape cutting mechanism, characterized in that the mechanism shaft includes a first mechanism shaft and a second mechanism shaft that are parallel to each other, the first mechanism shaft and the second mechanism shaft are connected by a transmission mechanism and rotate synchronously, and the first mechanism shaft or the second mechanism shaft is connected to the mechanism motor;
[0006] The cams controlling the swing of the slide plate arm and the hot-stick head arm are mounted on the first core shaft, and the cams controlling the lifting and lowering of the tape cutting mechanism are mounted on the second core shaft.
[0007] The strapping mechanism includes a swingable strapping assembly, the swing axis of which is perpendicular to the axis of the movement shaft, and the strapping assembly can move back and forth along the swing axis of the strapping assembly.

The cable management arm of the cable management assembly is located on the second side of the movement frame and performs the back-and-forth movement on the second side of the movement frame. The slide arm and the hot-stick head arm are located on the first side of the movement frame.
[0011] The motor that drives the belt assembly to swing is arranged perpendicularly to the core motor.
[0012] The pressing mechanism includes a first right pressing mechanism, which includes a pressed block and a first right pressing block. The pressed block and the first right pressing block cooperate to clamp the packing tape on the side connected to the tape roll at the cutter's cutting point.

The second right top block is a lifting component. A cam that controls the lifting of the second right top block is mounted on a second core shaft. The second right pressing block is movably connected to a second right pressing block swing arm. A cam that controls the swing of the second right pressing block swing arm is mounted on a first core shaft.
[0014] A cam controlling the forward and backward movement of the belt feeding assembly is mounted on the second core shaft, and a cam controlling the lifting and lowering of the belt pressing mechanism is also mounted on the second core shaft.

The division of labor is clear, and the structure is compact. Furthermore, it facilitates the distributed power drive and vertical layout of the strapping mechanism, further reducing the size of the mechanism in the width direction of the packing machine.

The core shaft includes a first core shaft 103 and a second core shaft 104 that are parallel to each other. One end of the first core shaft 103 is connected to the second core shaft 104 through a transmission mechanism, which is a gear connection structure.

[0029] Cam 502 is a cam that controls the lifting and lowering of the tape cutting mechanism. In the tape feeding direction, the one closer to the tape head 201 is the downstream (the tape head 201 refers to the head of the packing tape during the tape feeding movement, and the packing tape from the tape head 201 to the tape tail 202 is the packing tape that is cut by the cutter and tied to the object). The cutter 500 is located upstream of the hot-sticking head 400. The cutter 500 has a first left pressure block 501 that lifts and lowers synchronously with it and cooperates with the hot-sticking head 400 to press the hot-sticking part of the tape tail onto the hot-sticking head 400.
[0030] Cam 602 is a cam that controls the lifting and lowering of the second left pressure block 601 of the left top belt mechanism. The second left pressure block 601 is located to the left of the first left pressure block 501 and is used to press the portion of the packing strap head upstream of the heat-bonding part onto the slide plate 300.

The first right pressing mechanism includes a pressed block 701 and a first right pressing block 700, as shown below. Figure 3 As shown, the pressing block 701 and the first right pressing block 700 cooperate to clamp the packing tape 200 connected to the tape roll at the cutting point of the cutter (i.e., the tape head for the next packing). In the tape feeding direction, the side closer to the tape head is downstream, and the first pressing mechanism is located upstream of the cutter 500. The pressing block 701 is connected to the pressing block swing arm 703, and the cam 704 that controls the swing of the pressing block swing arm 703 is mounted on the first core shaft 103.

The second right pressing mechanism includes a second right pressing block 800 and a second right top block 801. The second right top block 801 and the second right pressing block 800 cooperate to push the second right pressing block upwards, pressing the end of the packing strap onto the slide plate 300. The second right top block 801 is a lifting component. The second right pressing block 800 is movably connected to the second right pressing block swing arm 803. Cam 804, which controls the swing of the second right pressing block swing arm 803, is mounted on the first core shaft 103.

[0034] The strapping assembly includes a swing arm 903 and a strapping component 900 movably connected to the swing arm. The strapping mechanism is equipped with a motor 905 that independently drives the strapping assembly to swing. The strapping component 900 is slidably connected to the swing arm 903 and can move away from and towards the swing axis of the strapping assembly during the swing. The strapping mechanism includes a lifting control mechanism, and the cam surface of a cam 906 that controls the movement of the strapping component away from and towards the swing axis of the strapping assembly rises and falls. The cam 904 controlling the lifting control mechanism is mounted on a second core shaft 104. The lifting control mechanism uses a lever 907.
[0035] The first core shaft 103 is located near the first side of the core frame 102, while the second core shaft 104 is located near the second side of the core frame 102. The swing arm 903 of the tape feeding assembly is located on the second side of the core frame 102 and performs the back-and-forth movement on the second side of the core frame. The slide arm and the hot-stick head arm are located on the first side of the core frame. The motor 905, which independently drives the tape feeding assembly to swing, is arranged perpendicularly to the core motor 101.
