Description

Technical Field

[0001] This utility model relates to the field of cardboard box packaging equipment technology, and in particular to a pressure device for an external gantry. Background Technology

[0002] A baling machine, also known as a strapping machine, strapping machine, or bundling machine, uses strapping tape to bundle products or packages, then tightens it and joins the ends using a heat-sealing head. The function of a baling machine is to reinforce packaged goods, preventing them from scattering during handling and storage due to loose strapping, while also ensuring neat and aesthetically pleasing bundling. When baling stacks of cardboard boxes, to ensure the boxes are securely stacked, a pressure device is typically installed in front of the strapping machine's output frame. This pressure device includes a gantry frame positioned in front of the output frame, arranged side-by-side with mounting frames on top. The mounting frames have four lifting rods at their four end points, with two symmetrical lifting rods connected by a connecting rod at the front and rear ends. The two lifting rods of the weighing device have pressure blocks at their bottoms, which are located on the front and rear sides of the conveyor belt frame. When a stack of cardboard boxes moves to the conveyor belt frame, the cylinder drives the pressure block on either side to move downwards. Since the left and right symmetrical lifting rods are connected to the pressure blocks, and the front and rear symmetrical lifting rods are connected in series by a connecting rod, the pressure blocks on the front and rear sides will move down together and press against the stack of cardboard boxes, thereby compressing the gaps between the cardboard boxes. However, since the gantry frame and the conveyor belt frame of the traditional pressing device are set up side by side, the span of the two symmetrical lifting rods is relatively large. This requires the use of a long connecting rod to connect the front and rear lifting rods together. However, the cylinder only drives the pressure block on one side to move. The large span of the pressure blocks on both sides seriously affects the synchronization of the front and rear pressure blocks, thus requiring higher connection between the lifting rods and causing great inconvenience to production. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressurization device for an external gantry, thereby effectively solving the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pressurizing device with an external gantry, including a packing machine and a tape output frame disposed above the packing machine. A gantry frame is disposed on the packing machine at a position corresponding to the outer side of the tape output frame. An installation frame is disposed on the gantry frame at a position above the tape output frame. A lifting frame that can move synchronously is symmetrically disposed on the left and right sides of the installation frame. An installation block is disposed at the lower end of the lifting frame at both the front and rear sides of the tape output frame. A pressure block is disposed at the lower end of the installation block.

[0005] The lifting frame includes lifting rods disposed on the front and rear sides of the mounting frame. The lifting rods pass through the mounting frame and are respectively disposed on the front and rear sides of the belt conveyor frame. The upper ends of the front and rear ends of the lifting rods are fixedly connected together by connecting plates. The mounting blocks are respectively disposed at the bottom ends of the front and rear lifting rods.

[0006] Furthermore, a drive cylinder is also provided on the top of the mounting frame, and the piston rod of the drive cylinder extends vertically downward through the mounting frame, and the piston rod of the drive cylinder is fixedly connected to the top of any of the mounting blocks.

[0007] Furthermore, the mounting block is connected to the left and right lifting rods, and a connecting block is provided on the top of the mounting block. The lower ends of the lifting rods and the piston rod of the drive cylinder are both fixed on the connecting block.

[0008] Furthermore, the mounting blocks on the front and rear sides are provided with guide brushes on opposite sides, and the guide brushes are arranged opposite each other.

[0009] Furthermore, the mounting block has a mounting head on one side opposite to the other, and the mounting head has a slot. The brush handle of the guide brush is inserted into the slot. The mounting head and the brush handle are fixedly connected by a quick-connect pin. The two brush handles are provided with brushes on one side opposite to the other.

[0010] Furthermore, the quick-install pin includes a pin rod, and the mounting head and brush handle are provided with insertion holes along the vertical direction. The insertion holes of the mounting head and brush handle are interconnected to form a pin hole for easy insertion of the pin rod. The top of the pin rod is provided with a rod head, and a telescopic spring is also sleeved on the upper end of the pin rod. The upper end of the telescopic spring abuts against the lower end of the rod head, and the lower end of the telescopic spring abuts against the top of the mounting head. A limiting protrusion is also provided on one side of the lower end of the pin rod. Vertical sliding grooves are provided on the mounting head and brush handle at positions corresponding to their respective insertion holes. The sliding grooves on the mounting head and brush handle cooperate with each other to form a channel for easy up and down movement of the limiting protrusion. The mounting head can move along the channel to the bottom end of the mounting head.

[0011] Furthermore, the bottom of the mounting head is provided with a limiting groove on one side of the corresponding insertion hole. The limiting groove is connected to the insertion hole and is located on the opposite side of the insertion hole. The limiting protrusion clamp is located in the limiting groove.

[0012] The above-mentioned technical solution of this utility model has the following beneficial effects: By setting a gantry frame that spans across itself on the outside of the conveyor frame, and setting an installation frame and lifting rod at the upper end of the gantry frame, the span between the front and rear lifting rods is reduced, which reduces the connection requirements between the front and rear symmetrical lifting rods. Furthermore, the reduced span between the lifting rods can better ensure the synchronicity of the movement of the front and rear pressure blocks, which greatly facilitates the assembly and use of the equipment.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4 As shown, the pressurizing device for an external gantry in this embodiment includes a packing machine 1 and a tape output frame 2 set above the packing machine 1. A gantry frame 3 is set across the packing machine 1 at a position outside the corresponding tape output frame 2. A mounting frame 4 is set above the corresponding tape output frame 2 on the gantry frame 3. A lifting frame that can move synchronously is symmetrically set on the left and right sides of the mounting frame 4. A mounting block 5 is set at the lower end of the lifting frame at both the front and rear sides of the corresponding tape output frame 2. A pressure block 6 is set at the lower end of the mounting block 5.

[0021] The lifting frame includes lifting rods 7 set on the front and rear sides of the mounting frame 4. There are four lifting rods 7 in total. The four lifting rods 7 are symmetrical in pairs in front and behind, and also symmetrical in pairs in the left and right. The lifting rods 7 pass through the mounting frame 4 and are respectively set on the front and rear sides of the belt frame 2. The upper ends of the front and rear lifting rods 7 are fixedly connected together by connecting plates 8. The mounting blocks 5 are respectively set at the bottom ends of the front and rear lifting rods 7.

[0022] The top of the mounting bracket 4 is also equipped with a drive cylinder 9. The piston rod of the drive cylinder 9 extends vertically downward through the mounting bracket 4, and the piston rod of the drive cylinder 9 is fixedly connected to the top of any mounting block 5.

[0023] The mounting block 5 is connected to the left and right lifting rods 4. A connecting block 10 is provided on the top of the mounting block 5. The lower ends of the lifting rods 7 and the piston rod of the drive cylinder 9 are fixed on the connecting block 10.

[0024] The mounting blocks 5 on the front and rear sides are provided with guide brushes 11 on the opposite side of each other, and the guide brushes 11 are arranged opposite each other.

[0025] Mounting block 5 has mounting head 12 on one side opposite to the other. Mounting head 12 has a slot. The brush handle 11a of guide brush 11 is inserted into the slot. Mounting head 12 and brush handle 11a are fixedly connected by quick-connect pin. Brush 11b is provided on one side opposite to the other on both sides of brush handle 11a.

[0026] The quick-install pin includes a pin rod 13, and the mounting head 12 and brush handle 11a are provided with insertion holes along the vertical direction. The insertion holes of the mounting head 12 and brush handle 11a are interconnected to form a pin hole for easy insertion of the pin rod 13. The top of the pin rod 13 is provided with a rod head 14, and the upper end of the pin rod 14 is also fitted with a telescopic spring 15. The upper end of the telescopic spring 15 abuts against the lower end of the rod head 14, and the lower end of the telescopic spring 15 abuts against the top of the mounting head 12. The pin rod 13 is also provided with a limiting protrusion 16 on one side of its lower end. The mounting head 12 and brush handle 11a are provided with vertical sliding grooves 17 at the positions corresponding to their respective insertion holes. The sliding grooves 17 on the mounting head 12 and brush handle 11a cooperate with each other to form a channel for easy up and down movement of the limiting protrusion 16. The mounting head 12 can move along the channel to the bottom end of the mounting head 12.

[0027] The bottom of the mounting head 12 is also provided with a limiting groove 18 on the side corresponding to the socket. The limiting groove 18 is connected to the socket and is located on the opposite side of the socket. The limiting protrusion 16 is clamped in the limiting groove 18.

[0028] The quick-release pin facilitates the disassembly and replacement of the guide brush 11. During installation, the brush handle 11a is inserted into the insertion hole of the mounting head 12. Then, the pin 13, which is fitted with a telescopic spring 15, is inserted along the insertion hole. The limiting protrusion 16 on the pin 13 is inserted into the corresponding position of the sliding groove 17. As the pin 13 passes through the mounting head 12 and the brush handle 11a, the rod head 14 at the upper end of the pin 13 will compress the telescopic spring 15, causing it to deform. At this time, the limiting protrusion 16 at the lower end of the pin 13 extends out at the lower end of the mounting head 12. Then, the pin 13 is rotated so that the limiting protrusion 16 rotates to the position of the limiting groove 18 at the bottom of the mounting head 12. The pin 13 is then released. Due to the compressive force on the telescopic spring 15, the limiting protrusion 16 will be locked in the limiting groove 18 under the action of its elasticity. At this time, the guide brush 11 is fixed on the mounting head 12. The whole process does not require the use of tools for tightening, making the operation convenient and quick.

[0029] The working principle of this utility model is as follows: stacked cardboard boxes are conveyed to the tape output frame 2. At this time, the drive cylinder 9 is started and its piston rod is extended. Under the action of the drive cylinder 9, the mounting block 5 on one side will move downward. Since the mounting blocks 5 on the front and rear sides are connected by the lifting rod 7 and the connecting plate 8, when the drive cylinder 9 drives the mounting block 5 on one side to move downward, the mounting blocks 5 on both sides will move synchronously. The pressure blocks 6 at the bottom of the mounting blocks 5 on both sides press on both sides of the stacked cardboard boxes. By pressing the cardboard boxes, the gap between the cardboard boxes is squeezed. Then the packing machine works, and the packing strap pops out in the tape output frame 2 and wraps around the stacked cardboard boxes, thereby completing the packing operation. After one packing operation is completed, the drive cylinder 9 will control the pressure blocks 6 on both sides to lift up. The packed cardboard boxes are conveyed to the subsequent equipment. The new stack of cardboard boxes is conveyed back to the tape output frame 2 and the above-mentioned pressure packing operation is repeated.

[0030] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
