[0023] Reference Figures 1 to 8 (The proportions of the sizes of the various components in the figure have been adjusted to clearly illustrate the coordination.) In one embodiment of the present invention, a pillow packaging machine for cables includes a front conveying section 100, a film feeding section 200 corresponding to the front conveying section 100, a forming plate 300 corresponding to the film feeding section 200, a middle sealing section correspondingly disposed downstream of the forming plate 300, an end sealing section 400 correspondingly disposed downstream of the middle sealing section, and a rear conveying section 500 correspondingly disposed downstream of the end sealing section 400. The front conveying section 100 includes: The longitudinal conveying unit 110 includes a frame 111 , a driving shaft 112 and a driven shaft 113 are mounted on the frame 111 , and a first conveyor belt 114 is mounted between the driving shaft 112 and the driven shaft 113 ; The motor 120 is configured to drive the driving shaft 112; The side conveying part 130 is arranged at one end of the width of the frame 111 and is located above the first conveyor belt 114. The side conveying part 130 includes a feeding component 131 and a transmission component 132. The transmission component 132 includes a first sliding seat 133 whose position is adjustable on the width of the frame 111 and a transmission shaft 134 rotatably mounted on the first sliding seat 133 and consistent with the length direction of the driving shaft 112. The two ends of the transmission shaft 134 are respectively a steering end 136 and a driven end 135. The driven end 135 forms a rotation transmission cooperation with the driving shaft 112. The feeding assembly 131 includes two second sliding seats 137 that are spaced apart along the length of the frame 111 and are adjustable in width. The two ends of the second sliding seat 137 are respectively a first bearing and a second bearing. A first rotating shaft 138 and a second rotating shaft 139 are respectively fixed and rotated between the two first bearings and the two second bearings. A second conveyor belt 140 is installed between the first rotating shaft 138 and the second rotating shaft 139. The end of the first rotating shaft 138 near the transmission shaft 134 forms a gear cooperation with the steering end 136 to form an intersecting axis or an staggered axis.

[0024] In the prior art, due to the special long shape of the cable, it is impossible to manually place the material by setting up a work station at the front conveying position, and it is also difficult to achieve automatic feeding; especially when multiple cables are installed in combination, the above problems are more serious.

[0025] In the present invention, the pillow packaging machine for cables includes a front conveyor section 100, a film feeding section 200 corresponding to the front conveyor section 100, a forming plate 300 corresponding to the film feeding section 200, a middle sealing section correspondingly arranged downstream of the forming plate 300, an end sealing section 400 correspondingly arranged downstream of the middle sealing section, and a rear conveyor section 500 correspondingly arranged downstream of the end sealing section 400. The front conveyor section 100 transports the pre-packaged cables downstream to the film feeding section 200 and the forming plate 300. The film delivery section 200 includes a mounting shaft for the film tube and a plurality of guide shafts, which are specifically designed to complete the film material delivery action. The film delivery section 200 delivers the film material to the forming plate 300, and the pre-packaged cable is accommodated by the special shape of the forming plate 300. Then, at the position of the middle sealing section, the film material is sealed in the width direction (the middle sealing section sometimes also assumes part of the responsibility of transporting the film material). Finally, the end sealing section 400 completes the sealing and cutting in the length direction to complete the pillow packaging process, and the rear conveying section 500 transmits the pre-packaged cable that has completed the packaging.

[0026] The front conveyor unit 100 includes a longitudinal conveyor unit 110, a motor 120, and a side conveyor unit 130. The longitudinal conveyor unit 110 includes a frame 111. A driving shaft 112 and a driven shaft 113 are mounted on the frame 111. A first conveyor belt 114 is mounted between the driving shaft 112 and the driven shaft 113. The rotation of the first conveyor belt 114 conveys the pre-packaged cables.

[0027] The motor 120 is provided corresponding to the driving shaft 112. The motor 120 can drive the driving shaft 112 through a belt or gears.

[0028] The side conveying portion 130 is disposed at one width end of the frame 111 and is located above the first conveyor belt 114 .

[0029] The side conveyor 130 includes a feed assembly 131 and a transmission assembly 132. The transmission assembly 132 comprises a first sliding seat 133, which is adjustable across the width of the frame 111, and a transmission shaft 134, rotatably mounted on the first sliding seat 133 and aligned with the length of the driving shaft 112. The transmission shaft 134 is terminated at its longitudinal ends by a steering end 136 and a cylindrical driven end 135. The driven end 135 forms a rotationally coupled connection with the driving shaft 112. The connection between the driving shaft 112 and the driven end 135 can be achieved through a belt drive or gear transmission, enabling the driving shaft 112 to drive the transmission shaft 134 in rotation.

[0030] The feeding assembly 131 includes two second sliding seats 137 spaced apart along the length of the frame 111 and adjustable in width. A first bearing and a second bearing are located at either end of the second sliding seat 137. A first rotating shaft 138 and a second rotating shaft 139 are rotatably secured between the first and second bearings, respectively. A second conveyor belt 140 is mounted between the first and second rotating shafts 138 and 139. The second sliding seats 137 allow the feeding assembly 131 to be adjusted across the width of the frame 111, thereby adapting to the size requirements of different packages. (The transmission assembly 132's adjustment across the width of the frame 111 also serves to match the position of the feeding assembly 131.) The end of the first rotating shaft 138 near the drive shaft 134 forms a gear-like arrangement with the steering end 136, forming an intersecting or staggered axis. Through this arrangement, the rotation of the driven shaft 113 is transmitted to the first rotating shaft 138, thereby enabling the feeding assembly 131 to complete the conveying operation. The conveying speed of the feeding assembly 131 matches the conveying speed of the longitudinal conveyor 110, and no adjustment is required (adjustment is required when the length of the pre-packaged cables changes). During use, the pre-packaged cables can be placed on the feeding assembly 131 while it is in operation, or the transmission assembly 132 of the side conveyor 130 can be separated from the feeding assembly 131 (in this case, the power of the driving shaft 112 is not transmitted to the first rotating shaft 138), and multiple pre-packaged cables can be placed on the stationary second conveyor belt 140. The driving transmission assembly 132 is then coupled to the feeding assembly 131, and the power of the driving shaft 112 is transmitted to the first rotating shaft 138. The feeding assembly 131 then begins normal operation, and the pre-packaged cables on it are sequentially conveyed to the longitudinal conveyor 110.

[0031] In summary, the side conveying part 130 is arranged at one end of the width of the frame 111 and is located above the first conveyor belt 114. One end of the transmission shaft 134 forms a transmission fit with the driving shaft 112, and the other end forms a gear fit with the first rotating shaft 138 to form an intersecting axis or an staggered axis. The feeding component 131 can be adjusted in the width direction of the frame 111 through the second sliding seat 137, so that it can adapt to the size requirements of different packages. The position adjustment of the transmission component 132 in the width direction of the frame 111 can match the position change of the feeding component 131; through the above cooperation, the rotation of the driven shaft 113 is transmitted to the first rotating shaft 138, so that the feeding component 131 can complete the conveying action, and the conveying speed of the feeding component 131 is matched with the conveying speed of the longitudinal conveying part 110, and no adjustment is required.

[0032] Reference Figure 8 In one embodiment, the driven end 135 of the transmission shaft 134 and the driving shaft 112 clamp the first conveyor belt 114 .

[0033] This embodiment provides a simple and efficient transmission method. The driven end 135 of the transmission shaft 134 is positioned above the driving shaft 112 and, together with the driving shaft 112, clamps the first conveyor belt 114 at that position. Because the driven end 135 of the transmission shaft 134 does not directly contact the driving shaft 112, when the transmission assembly 132 moves across the width of the frame 111, the driven end 135 of the transmission shaft 134 rotates along with the driving shaft 112. During operation, the rotation of the driving shaft 112 does not directly drive the transmission shaft 134. Instead, the driving shaft 112 drives the first conveyor belt 114, which in turn drives the transmission shaft 134.

[0034] Reference Figures 1 to 5 In one embodiment, the driven end 135 of the transmission shaft 134 is linked to the driving shaft 112 via a synchronous belt.

[0035] In this embodiment, a synchronous belt system is used to link the drive shaft 134 with the driving shaft 112. This simplifies fabrication and provides superior transmission efficiency. Furthermore, when the synchronous belt 141 engages the driven end 135 of the drive shaft 134, the drive shaft 134 can still slide longitudinally. Compared to a gear system that couples the drive shaft 134 to the driving shaft 112, the synchronous belt system provides greater spatial flexibility, facilitating installation and operation.

[0036] Reference Figures 6 to 7 In one embodiment, there are two side conveying parts 130 , and the other side conveying part 130 is arranged at the other end of the frame 111 in the width direction.

[0037] In this embodiment, since automatic grasping of pre-packaged cables is difficult, placement of the pre-packaged cables on the side conveyor 130 is often performed manually. Although the second conveyor belt 140 in the side conveyor 130 has a relatively slow transport speed, manually placing the pre-packaged cables on the second conveyor belt 140 is labor-intensive. By adding another side conveyor 130, the two side conveyors 130 can be operated intermittently. Specifically, after the transmission assembly 132 of one side conveyor 130 is separated from the feeding assembly 131, the power of the drive shaft 112 is not transmitted to the first rotating shaft 138. After multiple pre-packaged cables are placed on the stationary second conveyor belt 140, the transmission assembly 132 is coupled to the feeding assembly 131. At this point, the power of the drive shaft 112 is transmitted to the first rotating shaft 138, and the feeding assembly 131 begins normal operation. When one side conveyor 130 begins operating, the placement of the pre-packaged cables can begin on the other side conveyor 130, ultimately achieving alternating operation.

[0038] Reference Figures 1 to 5In one embodiment, a plurality of barrier strips 142 are arranged at intervals in the length direction on the outer surface of the second conveyor belt 140 , and the second conveyor belt 140 is inclined downward by 5 to 30 degrees toward the front conveying portion 100 .

[0039] In this embodiment, the placement of the pre-packaged cables on the second conveyor belt 140 is made simpler and more standardized by the provision of the barrier strips 142. The barrier strips 142 can be integrally formed or fixedly connected to the second conveyor belt 140. The barrier strips 142 are provided along the width direction of the second conveyor belt 140, but are not limited to being continuous, as long as they can complete the separation and blocking of the pre-packaged cables. Considering that the function of the barrier strips 142 is to accurately position the pre-packaged cables, and abnormal mutual movement may still occur between the pre-packaged cables and the second conveyor belt 140, the feeding process of the pre-packaged cables may be abnormal; then the provision of the barrier strips 142 is combined with the downward tilt of the second conveyor belt 140, so that the pre-packaged cables will be against the barrier strips 142 under the action of gravity, and while the position accuracy requirements for placing the pre-packaged cables are reduced, the position accuracy of the pre-packaged cables is also improved.

[0040] In one embodiment, the outer diameters of the first rotating shaft 138 and the second rotating shaft 139 are different, so that the second conveyor belt 140 is tilted downward.

[0041] In this embodiment, considering that the second sliding seat 137 is tilted and the second conveyor belt 140 is tilted downward, the height state of the second conveyor belt 140 will change, which will affect the feeding and the coordination process between the first rotating shaft 138 and other components; the first rotating shaft 138 and the second rotating shaft 139 are formed with a difference in outer diameter, so that the second conveyor belt 140 naturally tilts downward without the need to adjust other components.

[0042] In one embodiment, a first locking structure and a second locking structure are respectively provided corresponding to the first sliding seat 133 and the second sliding seat 137 .

[0043] In this embodiment, the first sliding seat 133 can be locked and released to the frame 111 through the first locking structure, and the second sliding seat 137 can be locked and released to the frame 111 through the second locking structure. The specific structures of the first locking structure and the second locking structure are not limited. For example, the first locking structure can be a threaded fixing bolt, which is screwed in and out of the frame 111 to achieve combination and release with the first sliding seat 133 on the frame 111.

[0044] In one embodiment, the transmission assembly 132 further includes a linear drive installed on the frame 111 and driving the transmission assembly 132 to reciprocate in the width direction of the frame 111 .

[0045] In this embodiment, the addition of a linear drive allows the transmission assembly 132 and the first rotating shaft 138 to be separated and connected automatically. The linear drive can be driven by pneumatic drive, hydraulic drive, motor drive, etc. Most workshops have compressed air circuits, so pneumatic drive is convenient.

[0046] In one embodiment, the inner end of the side conveying portion 130 further includes a baffle disposed on the second sliding seat 137 , and the baffle is disposed along the length direction of the longitudinal conveying portion 110 .

[0047] In this embodiment, position restriction is achieved by a baffle. After the pre-packaged cable falls from the side conveying portion 130 to the longitudinal conveying portion 110, it is restricted by the baffle, thereby restricting the position of the pre-packaged cable in the width direction.

[0048] Reference Figures 1 to 5 In one embodiment, the steering end 136 is in the shape of a bevel gear, and the end of the first rotating shaft 138 near the transmission shaft 134 is in the shape of a bevel gear.

[0049] In the aforementioned embodiment, the coupling method between the transmission shaft 134 and the driving shaft 112 is not limited; as long as the transmission shaft 134 can transmit the drive of the driving shaft 112 to the first rotating shaft 138, it is sufficient. In this embodiment, a method with simple structure and stable transmission is proposed. In particular, if the first rotating shaft 138 and the transmission shaft 134 need to be separated and coupled, the coupling method of two bevel gears can more conveniently achieve this requirement.

[0050] To sum up, in the pillow packaging machine for cables provided by the present invention, the side conveying part 130 is arranged at one end of the width of the frame 111 and is located above the first conveyor belt 114, one end of the transmission shaft 134 forms a transmission cooperation with the active shaft 112, and the other end forms a gear cooperation of an intersecting axis or an staggered axis with the first rotating shaft 138, and the feeding component 131 can be adjusted in the width direction of the frame 111 through the second sliding seat 137, so as to adapt to the size requirements of different packages, and the position adjustment of the transmission component 132 in the width direction of the frame 111 can match the position change of the feeding component 131; through the above cooperation, the rotation of the driven shaft 113 is transmitted to the first rotating shaft 138, so that the feeding component 131 can complete the conveying action, and the conveying speed of the feeding component 131 is matched with the conveying speed of the longitudinal conveying part 110, and no adjustment is required.
