Among them, the packing tape output by the belt feeding mechanism 21 enters into the guide belt groove 11 and is output from the guide belt groove into the sealing mechanism 22 .

Specifically, in the actual assembly process, the belt feeding mechanism 21 and the sealing mechanism 22 are assembled together to form the machine head body 2, and the machine head body 2 is installed on the sliding seat 12 on the installation base 1 as a whole layout, so as to Complete the assembly of the head for the strapping machine.

During use, the belt feeding mechanism 21 is used to drive the packing belt entering the strapping head to move. The belt opening 202 is outputted and entered into the guide belt groove 11 , and the packing belt enters the sealing mechanism 22 under the guiding action of the guide belt groove 11 . The packing tape can be fed into the packaging chute via the sealing mechanism 22 for delivery, and finally transported into the sealing mechanism 22 again.

The sealing mechanism 22 can weld and cut the packing tape, and in order to realize the tensioning of the packing tape, the sealing mechanism 22 is provided with a cutting element 221 and a welding element 222, the welding element 222 is used for welding the packing tape, and the cutting element 221 For cutting off strapping. For the specific representation entities of the cutting element 221 and the welding element 222 configured by the sealing mechanism 22, reference may be made to the structural design in the conventional strapping head, which will not be described and limited herein.

At the same time, in order to meet the requirements of tightening the packing belt, the sealing mechanism 22 further includes a first clamping mechanism 223, a second clamping mechanism 224 and a third clamping mechanism 225. The first clamping mechanism 223, the second clamping mechanism 223 and the second clamping mechanism The mechanism 224 and the third clamping mechanism 225 clamp the strapping. Wherein, for the concrete representation entities of the first clamping mechanism 223 , the second clamping mechanism 224 and the third clamping mechanism 225 , reference may be made to the clamping structures in the conventional technology, which are not limited or described herein.

Specifically, the first clamping mechanism 223 is arranged between the tape inlet 201 and the tape outlet 202, and along the conveying direction of the packaging tape, the first clamping mechanism 223 and the belt feeding mechanism 21 are arranged in sequence. The second clamping mechanism 224 , the cutting element 221 , the welding element 222 and the third clamping mechanism 225 are sequentially arranged on the lower part of the handpiece body 2 .

The packing belt first passes through the first clamping mechanism 223 and enters the belt feeding mechanism 21. The packing belt is driven by the belt feeding mechanism 21 and output to the guide belt groove 11 and guided into the sealing mechanism 22. The packing belt passes through the second clamping mechanism in turn. 224, the cutting element 221, the welding element 222 and the third clamping mechanism 225 are output to the external packaging chute, and are guided through the packaging chute to surround the goods and then return to the sealing mechanism 22. For the specific transmission process of the packaging tape, You can refer to the packing belt conveying process of the conventional strapping machine, which will not be repeated here.

Since the belt feeding mechanism 21 and the sealing mechanism 22 are integrated and installed on the sliding seat 12 together, it is convenient for the operator to disassemble the belt feeding mechanism 21 and the sealing mechanism 22 . In addition, during the tensioning process of the packing belt, the guiding belt groove 11 is used as a bearing part to bear the pulling force of the packing belt, so as to avoid applying the pulling force to the belt feeding mechanism 21 . The guide belt groove 11 has no power components and moving parts, so that it can effectively avoid the damage of the guide belt groove 11 due to excessive tension, and overcome the damage of the belt feeding mechanism 21 directly under the tension of the packing belt. , in order to improve the reliability of the head of the strapping machine.

More importantly, for the belt feeding mechanism 21, it generally includes a belt feeding pulley 211, a pinch pulley 212 and a second driving mechanism 213, the pinch pulley 212 is located above the belt feeding pulley 211, and the second driving mechanism 213 is configured There is a driving motor to drive the belt feeding pulley 211 to rotate, so that the packing belt is output through between the belt feeding pulley 211 and the pressing pulley 212 . Since the belt feeding mechanism 21 does not bear the tension of the packing belt during the tensioning process, the belt feeding mechanism 21 is only used for conveying the packing belt, so that the diameter of the belt feeding pulley 211 used by the belt feeding mechanism 21 is small, and because the guide belt The groove 11 replaces the belt feeder 211 as the main force-bearing component when tightening the packing belt, so that the size of the rotating shaft of the belt feeder 211 is also designed to be smaller. For the second driving mechanism 213 , the motor type configured therein is correspondingly smaller, which is more conducive to reducing the manufacturing cost.

There are various forms for the representation of the first drive mechanism 13, for example: the first drive mechanism 13 is an electric push cylinder, and the push rod of the electric push cylinder is connected to the sliding seat 12; or, the first drive mechanism 13 includes Drive motor, gear and rack, the gear is rotatably arranged on the mounting base 1, the rack is slidably mounted on the mounting base 1, the gear meshes with the rack, the drive The motor is connected with the gear, and the rack is connected with the sliding seat 12 .

Further, the installation base 1 is also provided with a support member 14 , and the guide belt groove 11 is provided on the support member 14 .

Specifically, since the packing belt exerts a relatively large pulling force on the guide belt groove 11 during the tightening process, in order to improve the overall structural strength of the guide belt groove 11 to improve its bearing capacity. Then, a support member 14 is arranged on the inner side of the guide belt groove 11. The support member 14 can effectively support the guide belt groove 11 on the inner side of the guide belt groove 11, and then the guide belt groove 11 is affected by the tension of the packing belt. The tensile force is transmitted to the support member 14 for effective support by the support member 14 . Among them, the support member 14 is located between the guide belt groove 11 and the sliding seat 12. When in use, the packing tape exerts a pulling force on the guide groove belt groove toward the sliding seat 12, and the support member 14 between the two can effectively provide support for the guide belt groove 11.

Preferably, the guide belt groove 11 includes a first sub-slot portion 111 and a second sub-slot portion 112 , the first sub-slot portion 111 is an arc-shaped structure, and the second sub-slot portion 112 is a strip-shaped structure; the first sub-slot portion 111 Located above the second sub-slot portion 112, the lower port of the first sub-slot portion 111 communicates with the second sub-slot portion 112, the first sub-slot portion 111 is arranged on the top and side of the support member 14, and the second sub-slot portion 111 112 is arranged laterally below the support member 14 .

Specifically, the guide belt groove 11 includes a first sub-groove portion 111 and a second sub-groove portion 112 that are connected together. The first sub-slot 111 has an arc-shaped structure as a whole and is disposed on the support member 14. On the one hand, the first sub-slot 111 is used to change the conveying direction of the packing tape, and on the other hand, the first sub-slot 111 is used to carry The tension that occurs when the strap is pulled tight. The second sub-groove 112 is mainly used for guiding and conveying the packing tape to the sealing mechanism 22 . After the packing tape enters the guide belt groove 11, it is first conveyed along the first sub-groove 111 and enters the second sub-groove 112. Then, the packing tape is output from the second sub-groove 112 and enters the sealing mechanism 22. .

Preferably, the bottom of the installation base is further provided with a return belt groove 16, and the return belt groove 16 is located below the second sub-slot portion. Specifically, in order to realize the functional integration design, a return belt groove 16 is arranged at the bottom of the installation base, and the packing belt output from the sealing mechanism 22 re-enters the sealing mechanism 22 through the return belt groove 16 after being guided around the goods for one week. , to meet the needs of tensioning and welding. Therein, when tensioned, the strapping will be disengaged from the return strap slot 16 to bind to the surface of the cargo. Wherein, for the return belt groove 16, it usually includes a fixing strip 161 and two fins 162, the fins are arranged on both sides of the fixing strip, and a supply space is formed between the fixing strip 161 and the two fins 162. The groove structure through which the packing belt passes, and the fins 162 can move relative to the fixing bar 161 to realize the opening and closing of the two fins, thereby satisfying the requirement that the packing belt is detached when tensioned, and the specific structural form of the return belt groove 16 can be With reference to the grooved structure in the conventional technology, no limitation or detailed description will be made here.

Specifically, on the one hand, the fixing strip is used to cooperate with the two fins 162 to form the return belt groove 16 , and on the other hand, the fixing strip is also used to cooperate with the supporting member to form the second sub-groove. In this way, the distance between the exit of the second sub-slot portion and the exit of the return belt groove 16 is relatively short, so that the packing tape can enter the sealing mechanism 22 , and at the same time, the second sub-slot portion is formed by sharing the fixing strip. 112 and the return belt groove 16 make the overall structure more compact and compact.

In addition, for the first sub-groove, the guide strip groove includes an arc-shaped shielding member 110 arranged on the outer side of the supporting member 14, and the arc-shaped shielding member 110 is connected to the supporting member. The first sub-groove portion 111 is formed between 14 .

Furthermore, in order to ensure smooth sliding of the sliding seat 12 and at the same time ensure that the sliding seat 12 can stably and reliably carry the handpiece body 2 . The other end of the mounting base 1 is provided with two parallel support guide rails 15 , two sides of the sliding seat 12 are respectively provided with guide grooves (not marked), and the support guide rails 15 are inserted into the guide grooves on the corresponding sides.

Specifically, the two supporting rails 15 formed by the mounting base 1 are used to install the sliding seat 12 , and the sliding seat 12 will slide along the two supporting rails 15 . The sliding seat 12 includes an installation frame 121 and two side sliding frames 122 . The side sliding frames 122 are disposed on corresponding sides of the installation frame 121 , and the guide grooves are formed between the side sliding frames 122 and the installation frame 121 . The mounting frame 121 is used for carrying the mounting head body 2 , and a guide groove is formed between the side sliding frame 122 and the mounting frame 121 to satisfy the cooperation with the support rail 15 . Since the sliding seat 12 adopts a split design, during assembly, the mounting frame 121 can be placed between the two support rails 15 first, and then the side sliding frame 122 can be mounted and fixed on the mounting frame 121 to facilitate the operation. Quick assembly by personnel. In order to ensure smooth sliding of the sliding seat 12 , the side sliding frame 122 is provided with rollers 123 arranged up and down, the rollers 123 are located in the guide grooves, and the support rail 15 is located between the rollers 123 arranged up and down.

Still further, in order to ensure that the packing tape can enter the sealing mechanism 22 smoothly, a guide sleeve (not marked) is also provided on the mounting frame 121 , and the guide sleeve is provided at the entrance of the tape passage 203 and the guide tape groove 11 . between exports.

Further, the head body 2 includes a casing 23, the upper part of the casing 23 is provided with a tape inlet 201 and a tape outlet 202, and the bottom of the casing 23 forms a belt passage 203; 212 are both rotatably arranged in the housing 23 and located between the tape inlet 201 and the tape outlet 202 , and the cutting element 221 and the welding element 222 are located above the tape passage 203 .

Specifically, for the machine head body 2, the belt feeding mechanism 21 and the sealing mechanism 22 share a casing 23, which on the one hand meets the installation requirements of the components in the belt feeding mechanism 21 and the sealing mechanism 22, and on the other hand can achieve a small size Integrated design.

How to combine the drawings to explain the specific use process of the strapping machine.

During the tape threading process, the packing tape enters the housing 23 through the tape inlet 201 and passes through the first clamping mechanism 223 and enters between the belt feeding pulley 211 and the pressing pulley 212 of the belt feeding mechanism 21. Under the driving action of 211, the packing tape is output from the tape outlet 202 into the guide belt groove 11, then, the packing belt is guided into the sealing mechanism 22 through the guide belt groove 11, and finally, the packing belt is output from the sealing mechanism 22 to the external The packaging chute is guided through the packaging chute to surround the goods and then back into the sealing mechanism 22 .

During the tensioning process, after the first clamping mechanism 223 and the second clamping mechanism 224 are used to clamp both ends of the packing belt, the first driving mechanism 13 drives the sliding base 12 to move away from the guide belt groove 11 . Since the first clamping mechanism 223 and the second clamping mechanism 224 are both installed and fixed in the head body 2, under the driving action of the first driving mechanism 13, the first clamping mechanism 223 and the second clamping mechanism 224 move synchronously , the first clamping mechanism 223 and the second clamping mechanism 224 will pull the packing belt at the same time, and the tensioning distance between the two ends of the packing belt is the same, and the packing belt is guided through the guide belt groove 11, so that the first clamping mechanism 223 and the second clamping mechanism 223 and the second The clamping mechanism 224 applies the same pulling force to both ends of the packing tape. In this way, it can be ensured that the two ends of the packing belt are uniformly stressed, and the uneven force on both ends of the packing belt can be avoided, resulting in different packing tightness levels on both sides of the goods, resulting in a reduction in packing quality. At the same time, since the two ends of the packing belt are balanced in force, it can be made of a material with a relatively common material, so as to reduce the manufacturing cost of the packing belt and reduce the overall packing cost.

In addition, during the conveying process of the packing belt through the belt conveying mechanism 21, the free end of the packing belt first enters the sealing mechanism 22 for output, is transported through the packing chute, and is finally transported to the sealing mechanism 22 again. Two layers of packing tapes are formed at the welding element 222 (for the specific conveying process, please refer to the packing tape conveying process of the strapping machine). After the tensioning operation of the packing tape is completed by the first clamping mechanism 223 and the second clamping mechanism 224, the packing tape can be cut and welded. At this time, the third clamping mechanism 225 will replace the first clamping mechanism 223 to clamp the packing tape, and at the same time, the first clamping mechanism 223 will release the packing tape, and the pair of cutting elements 221 will be output from the belt feeding mechanism 21 to the The packing tape of the sealing mechanism 22 is cut. Then, the packing tape whose front side of the third clamping mechanism 225 and the rear side of the second clamping mechanism 224 are stacked together is welded by the welding element 222, so that both ends of the packing tape are welded together and bind the goods. Finally, the second clamping mechanism 224 and the third clamping mechanism 225 release the packing tape to complete the packing operation.

Based on the above technical solution, optionally, the installation positions of the guide belt groove 11 and the machine head body 2 can also be exchanged, that is, the machine head body 2 is fixedly installed on the installation base 1, and the guide belt groove 11 and its installation positions can be replaced. Relevant accessory components are mounted on the sliding seat 12 . In this way, in the actual use process, when the packing belt is tightened, the sliding seat 12 drives the guide belt groove 11 to move, so as to realize the tightening of the packing belt.

Wherein, regarding the manner in which the above-mentioned motor output power realizes the transmission connection, the manner of adding a reducer to the rotating shaft of the motor may be adopted, which will not be limited or described here.
