Detailed Description

As shown in fig. 1, the horizontal encircling type binding machine comprises a rack 1, a lifting seat 2 and a tape-moving frame 3, wherein the lifting seat 2 is arranged on the rack 1 in a lifting way, the tape-moving frame 3 is arranged on the lifting seat 2, a binding tape is arranged in the tape-moving frame 3, and the building blocks can be bound by the contraction of the binding tape under the driving of a binding machine core.

As shown in fig. 2, the strapping machine core includes a case 4, in order to solve the problems in the prior art, in the present invention, a horizontally extending slide rail 40 is installed on the case 4, a slide seat 20 is installed on the lifting seat 2, the slide rail 40 is slidably disposed on the slide seat 20, and a tension spring 41 for restoring the case 4 is connected between the lifting seat 2 and the case 4. As shown in fig. 3, when the tying movement pulls the tying belt a, the tying belt a gradually contracts, and when the tying belt a ties an object, the tying movement gradually moves to the right under the reverse traction of the tying belt a, so that the acting force of the tying belt a on the corner C of the object is buffered, and the four corners of the object are stressed uniformly, so that the quality of the object is not affected; when the binding of the binding tape A is finished and the binding tape A is cut off, the tension spring 41 pulls the binding movement to the original position again to wait for the next work, and the process is circulated. It is worth mentioning here that the slide 20 can be mounted on the cabinet 4, while the slide 40 is mounted on the lifting base 2, in a manner equivalent to the above-described mounting. In addition, the phrase "a tension spring 41 for restoring the chassis 4 is connected between the lifter base 2 and the chassis 4" means that one end of the tension spring 41 is connected to the lifter base 2 (including a member connected to the lifter base 2), and the other end thereof is connected to the chassis 4 (including a member connected to the chassis 4).

As shown in fig. 4, the belt-moving frame 3 is provided with a belt-moving frame, the belt a moves in the belt-moving frame, the previous belt-moving frame is of an integral structure and is fixed, if the distance from the inner side of the belt-moving frame to the stack of articles is long (the distance can be different due to different sizes of the articles), the belt falls down for a certain distance due to gravity in the contraction process, so that the belt has a certain inclination after being bound, but not a horizontal state, which can lead to the looseness of the articles in the transportation process. In order to solve the problem, the structure of the belt moving frame is improved, and the specific structure is as follows: the tape-walking frame comprises a front tape-walking frame 35 and a left side tape-walking frame and a right side tape-walking frame 36, wherein the front tape-walking frame 35 is arranged on a support 30, two ends of the support 30 are both connected with a slide block 38, in addition, two sides of the tape-walking frame 3 are both provided with a guide rail 39, the slide block 38 is arranged on the guide rail 39 in a sliding way, and the slide block 38 is in transmission connection with a power source for driving the slide block 38 to move on the guide rail 39.

The working principle is as follows: when the binding is to be carried out, the power source (motor) drives the sliding seat to move on the guide rail 39, so that the support 30 and the front belt moving frame 35 move forwards together, the range of the binding belt is reduced, after the range is reduced to a set range, the front belt moving frame 35 does not move forwards any more, and finally the binding machine drives the binding belt to contract, and the binding belt immediately binds the object. Through the structure, the binding belt can not fall off when being bound, the binding belt is more horizontal, and the binding effect is better.

In order to drive the sliding block 38 to move on the guide rail 39, the invention is provided with driving belt mechanisms on both sides of the belt travelling frame 3, each driving belt mechanism comprises a driving belt 34 and two driving belt wheels 31 (equal to a driving chain and a driving chain wheel), the driving belt 34 is wound on the two driving belt wheels 31, the two driving belt wheels corresponding to the two driving belt mechanisms are connected through a connecting shaft 32, and the driving belt wheel 31 of one driving belt mechanism is in driving connection with a power source. When the belt conveyor works, the power source drives the transmission belt wheels 31 of one of the transmission belt mechanisms to rotate, the two transmission belt wheels 31 synchronously rotate through the transmission of the transmission belts 34 of the transmission belt mechanism, the transmission belt mechanism drives the other transmission belt mechanism to synchronously act through the connecting shaft 32, and therefore the sliding blocks 38 on the left side and the right side drive the support 30 to move together with the forward belt conveying frame 35. Because the left and right sliding blocks 38 move synchronously, the forward belt frame 35 moves more stably without failure.

In order to allow the cable tie to smoothly transition from the side belt frame 36 to the front belt frame 35, the invention has a corner belt frame 37 between the front belt frame 35 and the side belt frame 36, the corner belt frame 37 being connected to the belt frame 3. The corner belt-walking frame 37 has the function of enabling the ribbon to be turned, and the ribbon can be smoothly formed into a ring shape.

In order to avoid the hard collision between the front belt-moving frame 35 and the belt-moving frame 3, the invention is provided with a rubber pad at the rear side of the front belt-moving frame 35. When the front belt frame 35 retreats, the front belt frame 35 does not suffer from hard collision due to the existence of the rubber pad, so that the front belt frame 35 is protected from being damaged.

As shown in fig. 5, the strapping movement includes a case 4, a strap pulling mechanism and a strap exit frame 8 are disposed in the case 4, as shown in fig. 6, the strap pulling mechanism includes a main traction wheel 5, a slave traction wheel 6 and a traction power source for driving the main traction wheel 5 to rotate, as shown in fig. 6, the main traction wheel 5 rotates by the driving of the traction power source, so that the main traction wheel 5 cooperates with the slave traction wheel 6 to pull and transmit a strap a, a rotatable strap pressing seat 9 is disposed in the case 4, a stressed wheel 7 is connected to the strap pressing seat 9, the stressed wheel 7 is close to the strap exit frame 8, as shown in fig. 7, the strap exit frame 8 is curved and has a strap exit 83, the strap exit 83 of the strap exit frame 8 faces the stressed wheel 7, as shown in fig. 6, a strap space 80 for gradually straightening a strap is disposed between an inlet end 81 of the strap exit frame 8 and an outlet end 82 of the strap, the stressed wheel 7 is disposed in the strap space 80, and the strap exit frame 6 is rotatably mounted on the traction wheel seat 14, and a connecting rod driving wheel seat 14 is connected to the strap exit 9.

The working principle of the bundling movement is as follows: as shown in fig. 9, when the bandage a is contracted, the traction power source drives the main traction wheel 5 to rotate, the main traction wheel 5 is matched with the slave traction wheel 6 to pull the bandage a backwards, the belt outlet frame 8 is bent and is provided with a belt outlet 83, so that the bandage a is stretched straight gradually in a bandage space 80 between an inlet end 81 and an outlet end 82 of the belt outlet frame 8, the bandage a has force F1 acting on the force receiving wheel 7 in the stretching process, as shown in fig. 6, the force receiving wheel 7 is mounted on the rotatable bandage seat 9, so that the bandage seat 9 starts to rotate, the bandage seat 9 is in transmission connection with the wheel seat 14 mounted with the slave traction wheel 6 through a connecting rod 10 to move, so that the slave traction wheel 6 presses the main traction wheel 5 with force F2, the pressure of the two wheels on the bandage a gradually increases, the straighter the bandage a in the bandage space is as the bandage a is tightened, the rotation angle of the bandage seat 9 increases, the bandage a is compressed, the bandage a is more easily, and the traction belt a is more firmly tied.

The connecting rod 10 on the belt pressing seat 9 can drive the wheel seat 14 to move to have various transmission structures, and only the transmission wheel seat 14 can lean against the main traction wheel 5 (the transmission structure is different), and the invention particularly provides a transmission structure: as shown in fig. 6, a rotatable swing member 11 is mounted on the chassis 4, one end of a connecting rod 10 is hinged to the belt pressing base 9, the other end of the connecting rod 10 is hinged to the swing member 11, a transmission rod 12 is hinged to the swing member 11, the transmission rod 12 is hinged to one end of a swing arm 13, the middle of the swing arm 13 is hinged to the chassis 4, and a wheel base 14 is hinged to the other end of the swing arm 13. Through the structure, when the belt pressing seat 9 rotates, the swing part 11 can be driven through the connecting rod 10, the swing part 11 drives the swing arm 13 to rotate through the transmission rod 12, the swing arm 13 drives the wheel seat 14 to move upwards or downwards, and therefore the driven traction wheel 6 on the wheel seat 14 presses the main traction wheel 5 or leaves the main traction wheel 5.

In order to provide a larger friction force, the invention provides two slave traction wheels 6, wherein two slave traction wheels 6 are arranged on the wheel seat 14, and two slave traction wheels 6 are close to the master traction wheel 5. The two slave traction wheels 6 can increase the friction force with the cable tie A, so that greater traction force can be brought to the cable tie A, and the cable tie is ensured not to slip.

In order to allow the cable tie A to pass between the main traction wheel 5 and the two auxiliary traction wheels 6 more smoothly in the case of two auxiliary traction wheels 6, as shown in FIG. 8, the invention is provided with a belt passing piece 15 arranged on the wheel seat 14, wherein the belt passing piece 15 is provided with a belt passing surface positioned between the two auxiliary traction wheels 6, and two sides of the belt passing surface are provided with belt blocking plates 16. The strap passing surface can prevent the cable tie A from being clamped between the two slave traction wheels 6, and the strap blocking plate 16 can ensure that the cable tie A is always positioned between the master traction wheel 5 and the slave traction wheels 6 and cannot be shifted to the outside.

Finally, it is worth mentioning that, in order to be able to synchronously drive the rotation of the slave traction wheel 6, a driving gear 50 is mounted on the wheel shaft of the master traction wheel 5, and a driven gear 60 is mounted on the wheel shaft of the slave traction wheel 6, the driven gear 60 being engaged with the driving gear 50. When the traction power source drives the main traction wheel 50 to rotate, the driven gear 60 and the driving gear 50 are in transmission, and the driven traction wheel 6 also rotates synchronously. When the main traction wheel 5 rotates clockwise, the auxiliary traction wheel 6 rotates anticlockwise, and the two wheels cooperate to pull the cable tie A. Certainly, the slave traction wheel 6 can not actively rotate, and can rotate along with the rotation of the main traction wheel 5 after being pressed with the main traction wheel 5, but the slave traction wheel 6 actively rotates to provide larger traction force, and the bundling effect of the ribbon is better.
