Description

Technical Field

[0001] This utility model relates to the field of carton packaging technology, specifically a carton tape pressing device. Background Technology

[0002] Cardboard boxes are packaging containers made primarily of cardboard (such as corrugated paper, kraft paper, etc.). They are widely used in commodity transportation, warehousing, and display, offering advantages such as protecting goods, facilitating handling, and being environmentally friendly and recyclable. In actual production, mass-produced products are packaged in cardboard boxes using assembly line operations. The end of the assembly line is equipped with box-sealing equipment to seal and pack the products, making them easy to store and transport. In related technologies, such as the carton tape pressing device in patent CN222408799U, the carton is moved between two sets of guide supports by an auxiliary roller. The distance between the two sets of guide supports can be adjusted by driving a second motor. After adjustment, the first motor is started to drive the guide wheel on one side to rotate, while the guide wheel on the other side plays an auxiliary rolling role, which improves the smoothness of transporting the carton. Under the action of the active guide wheel, the carton can be moved from one end of the transmission platform to the other end. When moving the carton, the telescopic rod is driven to lower the pressure plate until the pressure wheel corresponds to the position of the carton tape. When the carton is moved from one end of the transmission platform 1 to the other end, the tape is further pressed onto the carton.

[0003] The aforementioned device and technical solution still have some shortcomings in practical applications. Because the middle section of the transmission platform is a planar structure without any conveying aids, and the pressure rollers at the top cause significant frictional resistance between the carton and the bottom platform when tightening the tape, relying solely on one side of the active guide roller makes it difficult to smoothly push and convey the carton. Furthermore, the packaged carton contains products, and the added weight further exacerbates the resistance and makes it difficult to push, resulting in certain irrationalities in the structural design and practicality of the device. Therefore, a carton tape tightening device is provided to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a carton tape pressing device to solve the problems mentioned in the background art. In the prior art, the carton tape pressing device has a planar structure in the middle of the transmission platform and no transmission assistance measures. When the top pressure roller presses the tape, it causes the carton to form a large frictional resistance with the bottom platform. If only one active guide wheel is used, it is difficult to push the carton smoothly. In addition, the packaged carton contains products, and the counterweighted carton further aggravates the resistance and makes it difficult to push. Therefore, the device has certain unreasonable problems in terms of structural design and practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carton tape pressing device, which includes a conveying platform, a stabilizing support device, a lifting gantry frame, and a pressing assembly;

[0007] The conveying platform is composed of a first conveyor belt and a second conveyor belt located at the output end of the first conveyor belt, wherein the top surface of the first conveyor belt is higher than the top surface of the second conveyor belt;

[0008] The stabilizing support device includes fixed seats fixed to both sides of the conveying platform and located at the input end of the second conveyor belt. The opposite surfaces of the two fixed seats are provided with L-shaped support plates facing each other at an inner right angle. A clamping plate is vertically placed on one side of the L-shaped support plate at the inner right angle. An elastic telescopic component is horizontally connected between the L-shaped support plates and their vertical sections. The fixed seats are also provided with cylinders for driving the L-shaped support plates on both sides to move relative to each other and away from each other.

[0009] The lifting gantry frame is used to drive the pressing assembly to move up and down;

[0010] The clamping assembly includes a mounting plate located directly above the input end of the second conveyor belt, an elastic pressure plate located directly below the mounting plate, elastic connectors vertically connected to the four corners of the elastic pressure plate and the mounting plate, and a vibration motor mounted on the elastic pressure plate.

[0011] As a preferred embodiment of the carton tape pressing device of this utility model, the elastic telescopic component includes a plurality of guide posts with one end horizontally fixed to the side of the clamping plate facing the vertical section of the L-shaped tray, a sliding sleeve fixed on the L-shaped tray and slidingly matched with the plurality of guide posts, and a plurality of first springs connected between the vertical section of the L-shaped tray and the clamping plate.

[0012] The top surface of the horizontal section of the L-shaped pallet is lower than the top surface of the first conveyor belt, and the L-shaped pallet is adjacent to the output end of the first conveyor belt.

[0013] In a preferred embodiment of the carton tape pressing device of this utility model, a number of ball bearings are distributed along the length of the top surface of the horizontal section of the L-shaped tray.

[0014] As a preferred embodiment of the carton tape pressing device of this utility model, the lifting gantry frame includes a support frame that is horizontally fixedly installed on both sides of the conveying platform and a hydraulic rod that is vertically installed on the upper end of the support frame and used to drive the mounting plate to move up and down.

[0015] In a preferred embodiment of the carton tape pressing device of this utility model, the elastic pressure plate includes a base plate located directly below the mounting plate and a silicone pad located at the bottom of the base plate.

[0016] As a preferred embodiment of the carton tape pressing device of this utility model, the elastic connecting member includes a guide rod that is vertically fixed to the four corners of the upper end of the base plate and passes through the mounting plate, a limiting plate fixed to the top of the guide rod, and a second spring sleeved on the upper section of the guide rod. The upper end of the second spring abuts against the bottom surface of the limiting plate and the lower end abuts against the top surface of the mounting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When this carton tape pressing device is in use, when the first conveyor belt sends the carton to the second conveyor belt, due to the height difference, the carton will fall smoothly onto the L-shaped pallets on both sides. After the carton is completely separated from the first conveyor belt, the L-shaped pallets on both sides, under the action of the cylinder, use the elastic telescopic components and clamps to elastically clamp and stabilize the carton, so that the carton is suspended in the air. In this way, the elastic pressure plate at the top then descends and quickly and tightly presses the tape and the carton together. After the pressing is completed, the L-shaped pallets on both sides will separate from the carton one after another or simultaneously, so that the carton falls onto the second conveyor belt to continue to be conveyed backward. This cycle is repeated for the next round of tape pressing. The overall structure and usage are more scientific and reasonable than the prior art, and the practicality is further improved.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figures 1-3 The diagram shown is a complete structural schematic of a cardboard box tape pressing device according to this utility model. Please refer to [link / reference]. Figures 1-3This embodiment of a carton tape pressing device includes a conveyor platform 100, a stabilizing support device 200, a lifting gantry frame 300, and a pressing assembly 400. The upper part of the conveyor platform 100 is composed of a first conveyor belt 110 and a second conveyor belt 120 located at the output end of the first conveyor belt 110. The top surface height of the first conveyor belt 110 is higher than the top surface height of the second conveyor belt 120. The stabilizing support device 200 includes fixed seats 210 fixed to both sides of the conveyor platform 100 and located at the input end of the second conveyor belt 120. The opposing surfaces of the two fixed seats 210 are provided with L-shaped support plates 220 facing each other at an inner right angle. The L-shaped support plates 220 are located at one of the inner right angles. A clamping plate 230 is placed vertically on the side. An elastic telescopic component 240 is horizontally connected between the vertical sections of the L-shaped support plate 220 and the L-shaped support plate 220. A cylinder 250 is also provided on the fixed base 210 for driving the L-shaped support plates 220 on both sides to move relative to each other and away from each other. The lifting gantry frame 300 is used to drive the pressing component 400 to move up and down. The pressing component 400 includes a mounting plate 410 located directly above the input end of the second conveyor belt 120, an elastic pressure plate 420 located directly below the mounting plate 410, elastic connectors 430 vertically connected to the four corners of the elastic pressure plate 420 and the mounting plate 410, and a vibration motor 440 provided on the elastic pressure plate 420.

[0026] In this embodiment, the elastic telescopic assembly 240 includes a plurality of guide posts 241 with one end laterally fixed to the side of the clamping plate 230 facing the vertical section of the L-shaped pallet 220, a sliding sleeve 242 fixed to the L-shaped pallet 220 and slidably matched with the plurality of guide posts 241, and a plurality of first springs 243 connected between the vertical section of the L-shaped pallet 220 and the clamping plate 230; wherein, the top surface height of the horizontal section of the L-shaped pallet 220 is lower than the top surface height of the first conveyor belt 110, and the L-shaped pallet 220 is adjacent to the output end of the first conveyor belt 110. A plurality of ball bearings 221 are distributed along the length direction of the top surface of the horizontal section of the L-shaped pallet 220. It is understandable that when the L-shaped pallets 220 on both sides retract and release the carton placed on the horizontal section of the L-shaped pallet 220, the ball bearings 221 effectively reduce the frictional resistance between the carton and the L-shaped pallet 220, allowing the carton to land stably on the second conveyor belt 120. It should be noted that the second conveyor belt 120 has a latex pad on its surface, which cushions the carton and product falling onto it. Simultaneously, the distance between the top surface of the horizontal section of the L-shaped pallet 220 and the top surface of the second conveyor belt 120 is less than or equal to 2 cm, and the height difference should not be too large. Specifically, in use, when the first conveyor belt 110 sends the carton to the second conveyor belt 120, due to the height difference... Because of the difference, the carton will fall smoothly onto the L-shaped pallets 220 on both sides. After the carton is completely separated from the first conveyor belt 110, the L-shaped pallets 220 on both sides, under the action of the cylinder 250, and with the help of the elastic telescopic component 240 and the clamping plate 230, will elastically clamp and stabilize the carton. The bottom of the carton will not contact the top surface of the second conveyor belt 120. In this way, the elastic pressure plate 420 located above can smoothly press the tape of the carton. After pressing, the L-shaped pallets 220 on both sides will separate from the carton one after another or simultaneously, so that the carton falls onto the second conveyor belt 120 and continues to be conveyed backward. This cycle is repeated to carry out the next round of tape pressing work. Compared with the existing technology, it is more reasonable in terms of structural design and use.

[0027] In this embodiment, the lifting gantry 300 includes a support frame 310 horizontally fixedly installed on both sides of the conveyor platform 100, and a hydraulic rod 320 vertically installed on the upper end of the support frame 310 for driving the mounting plate 410 to move up and down. The elastic pressure plate 420 includes a base plate 421 located directly below the mounting plate 410, and a silicone pad 422 located at the bottom of the base plate 421. It is understood that the silicone pad 422 has good elasticity and gap filling properties, and can effectively compress the tape and the carton. The elastic connector 430 includes a guide rod 431 vertically fixed to the four corners of the upper end of the base plate 421 and passing through the mounting plate 410, a limiting plate 432 fixed to the top of the guide rod 431, and a second spring 433 sleeved on the upper section of the guide rod 431. The upper end of the second spring 433 abuts against the bottom surface of the limiting plate 432 and the lower end abuts against the top surface of the mounting plate 410. Specifically, during use, once the stabilizing brackets 200 on both sides are firmly secured to the carton brackets, the hydraulic rod 320 will drive the mounting plate 410 and other components to gradually descend until the elastic pressure plate 420 presses against the tape. At the same time, with the cooperation of the elastic connector 430, the vibration motor 440, and the silicone pad 422, the tape and the carton can be quickly and thoroughly pressed together.

[0028] In summary, the carton tape pressing device of this embodiment, when used, when the first conveyor belt 110 sends the carton to the second conveyor belt 120, due to the height difference, the carton will smoothly fall onto the L-shaped pallets 220 on both sides. After the carton is completely separated from the first conveyor belt 110, the L-shaped pallets 220 on both sides, under the action of the cylinder 250, and with the help of the elastic telescopic component 240 and the clamping plate 230, elastically clamp and stabilize the carton, so that the carton is suspended in the air. In this way, the elastic pressure plate 420 located above then descends and quickly and tightly presses the tape and the carton together. After the pressing is completed, the L-shaped pallets 220 on both sides will separate from the carton one after another or simultaneously, so that the carton falls onto the second conveyor belt 120 and continues to be conveyed backward. This cycle is repeated for the next round of tape pressing. The overall structure and usage are more scientific and reasonable than the existing technology, and the practicality is further improved.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
