Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, and more specifically to a tape pressing mechanism and a carton sealing machine. Background Technology

[0002] In industrial production, especially light industry, corrugated cardboard boxes are widely used for packaging products and sealed with self-adhesive tape. This method is inexpensive and easy to handle. In small-scale production, tape is mostly applied manually. However, in large and medium-sized integrated production, manual sealing is not only labor-intensive and slow, but also produces poor appearance quality. Therefore, the packaging industry at home and abroad has gradually adopted automatic box sealing machines to replace manual labor.

[0003] Most existing carton sealing machines use conveyor belts to transport cartons forward, with guide rails on both sides of the conveyor belt to guide the carton to move along a preset trajectory and complete the tape sealing during this process. However, the tape on the side panels of the carton is often not pressed tightly and bonded, causing the carton flap to pop open in subsequent processes. This requires manual re-pressing of the tape on the side panels, resulting in production interruptions and increased operating and material costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tape pressing mechanism and a box sealing machine that can effectively press the tape on the flip cover and side panel of the box.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, a tape pressing mechanism is provided, including a first pressing mechanism and a second pressing mechanism arranged back and forth along the travel direction of the box body. The first pressing mechanism and the second pressing mechanism have the same structure, each including a driving component and a pressing execution component. The driving component is connected to the pressing execution component and is used to drive the pressing execution component to reciprocate in the direction of approaching / moving away from the box body, so as to realize the sequential pressing of the tape at the box body flap and side panel.

[0006] The further technical solution is as follows: the initial pressing working surface of the pressing execution component in the first pressing mechanism protrudes beyond the initial pressing working surface of the pressing execution component in the second pressing mechanism in the direction of the box's travel.

[0007] The further technical solution is as follows: the clamping execution component includes a clamping member and a drive bracket. The clamping member is installed at the front end of the drive bracket. The drive component is installed on one side of the conveyor belt in the direction of travel of the box through a fixing plate. The drive component is connected to the drive bracket to drive the clamping member to reciprocate in the direction of approaching / moving away from the box.

[0008] The further technical solution is as follows: the drive bracket includes a connecting rod, two support rods respectively connected to the rear ends of the connecting rod, and two fixing blocks respectively extending forward from the ends of the connecting rod. The clamping member is rotatably installed between the two fixing blocks, and the drive assembly is connected to the connecting rod.

[0009] The further technical solution is as follows: the first pressing mechanism and the second pressing mechanism both include a guide assembly. The guide assembly includes at least one guide member. The guide member is connected to the fixed plate and a groove is formed on the guide member. The end of the drive bracket passes through the groove of the guide member and moves in the groove under the drive of the drive assembly.

[0010] The further technical solution is as follows: the guide includes a mounting plate and at least one roller assembly. Each roller assembly includes two guide rollers arranged side by side on the mounting plate. A groove is formed between the two guide rollers. The mounting plate is connected to the fixing plate. The end of the drive bracket passes through the groove.

[0011] The further technical solution is as follows: there are two mounting plates and two roller assemblies. The two roller assemblies are arranged side by side between the two mounting plates. The end of the drive bracket passes through the grooves of the two roller assemblies in sequence and can move within the grooves.

[0012] The further technical solution is as follows: the clamping component is a clamping roller, a clamping brush, or a clamping scraper.

[0013] A further technical solution is as follows: the drive assembly includes a cylinder, the cylinder barrel of the cylinder is fixed to the fixed plate, and the piston rod of the cylinder is connected to the drive bracket.

[0014] To solve the above-mentioned technical problems, according to another aspect of the present invention, a carton sealing machine is provided, including a conveyor belt mechanism, a controller, and a plurality of the above-mentioned tape pressing mechanisms, wherein the plurality of tape pressing mechanisms are symmetrically arranged on both sides of the conveyor belt mechanism along the forward direction of the carton, and the controller is electrically connected to the tape pressing mechanisms and the conveyor belt mechanism to control the operation of the conveyor belt mechanism and the tape pressing mechanisms.

[0015] Compared with the prior art, the tape pressing mechanism of this utility model is provided with a first pressing mechanism and a second pressing mechanism arranged back and forth along the direction of travel of the box. Both the first pressing mechanism and the second pressing mechanism include a driving component and a pressing execution component. The driving component can drive the pressing execution component to reciprocate in the direction of approaching / moving away from the box, so as to realize the sequential pressing of the tape on the box flap and side panel. That is, when the box or other box moves to the first pressing mechanism located in front, the pressing execution component at the first pressing mechanism can contact the tape on the moving box flap and always press the tape on the flap. As the tape is pressed, the box continues to move forward. When the side panel of the box contacts the second pressing mechanism located at the rear, the first pressing mechanism contacts the junction of the box flap and the other side panel. Driven by their respective drive components, they move towards the box, pressing the tape at the junction of the flap and the side panel onto the side panel. This greatly improves the bonding area and reliability of the tape on the side panel, preventing the box flap from popping open in subsequent processes. It can be seen that the tape pressing mechanism of this utility model can achieve automatic and effective pressing of the tape at the box flap and side panel positions without manual intervention, which can improve production efficiency and reduce costs.

[0024] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0025] Reference Figures 1 to 8 , Figures 1 to 8 A specific embodiment of the tape pressing mechanism 100 of this utility model is shown. In the embodiment shown in the figures, the tape pressing mechanism 100 includes a travel direction along the housing 400 (e.g., Figure 1 The first pressing mechanism 10 and the second pressing mechanism 20 are arranged in front and behind (as indicated by the arrow direction). The first pressing mechanism 10 and the second pressing mechanism 20 have the same structure, both including a driving component and a pressing execution component. Specifically, the first pressing mechanism 10 includes a driving component 11 and a pressing execution component 12, and the second pressing mechanism 20 includes a driving component 21 and a pressing execution component 22. The driving component 11 and the driving component 21 are respectively connected to the pressing execution component 12 and the pressing execution component 22 to drive the pressing execution component 12 and the pressing execution component 22 to reciprocate in a direction closer to / away from the box body 400, thereby achieving sequential pressing of the tape on the flip-top and side panels of the box body 400. In this invention, when the box body 400 (such as a cardboard box) moves to the first pressing mechanism 10 located in front, the pressing execution component 12 of the first pressing mechanism 10 contacts the tape on the flip-top of the moving box body 400 (e.g., ...). Figure 2 As shown), under the action of the drive assembly 11, the tape pasted on the flip cover is continuously pressed. The box 400 continues to move forward. When the side panel of the box 400 contacts the second pressing mechanism 20 located at the rear, the first pressing mechanism 10 contacts the junction of the flip cover and the other side panel of the box 400. Under the drive of their respective drive assemblies (11, 21), they move towards the box 400, pressing the tape at the junction of the flip cover and the side panel onto the side panel. This greatly improves the bonding area and reliability of the side panel tape, so as to prevent the flip cover of the box 400 from popping open in subsequent processes. It realizes the automatic and effective pressing of the tape at the position of the flip cover and the side panel of the box 400 without manual processing, which can improve production efficiency and reduce costs.

[0026] Preferably, in this embodiment, refer to Figure 1 and Figure 2The initial pressing working surface of the pressing execution component 12 in the first pressing mechanism 10 protrudes beyond the initial pressing working surface of the pressing execution component 12 in the second pressing mechanism 20 in the traveling direction of the housing 400. As shown in the figure, in this embodiment, the direction of travel of the box 400 is from right to left. Based on the above design, the flip-top of the box 400 is usually slightly raised. Since the initial pressing working surface of the first pressing mechanism 10 arranged on the right (i.e., the initial contact surface between the pressing execution component 12 and the box 400) is higher than the initial pressing working surface of the second pressing mechanism 20 located on the left (the initial contact surface between the pressing execution component 22 and the box 400), the pressing execution component 12 on the right side always performs a pressing action on the tape on the flip-top as the box 400 moves from right to left. This ensures that the tape at the edge of the flip-top (i.e., the tape at the junction of the flip-top and the side panel) is also fully compacted, ensuring that the tape is subjected to sufficient and uniform pressure in all key areas, which greatly improves the reliability and area of ​​the bonding. Understandably, the distance between the first pressing mechanism 10 and the second pressing mechanism 20 can be adjusted according to the size of the box, and the height difference between the initial pressing working surfaces of the first pressing mechanism 10 and the second pressing mechanism 20 can be adjusted according to the degree of lifting of the flip cover.

[0027] Continue to refer to Figures 3 to 8 , Figures 3 to 8 Taking the first pressing mechanism 10 as an example, the specific structure of the pressing mechanism is shown. In some embodiments, the driving assembly 11 includes a cylinder 111, the cylinder barrel 1111 of which is fixed on a fixing plate 30, and is mounted on one side of the conveyor belt 200 in the direction of travel of the box via the fixing plate 30. Figure 1 and Figure 2 The fixing plate 30 is bolted to an L-shaped plate 300 and fixed to one side of the conveyor belt 200 via the L-shaped plate 300. The pressing execution assembly 12 includes a pressing member 122 and a drive bracket 121. Preferably, in this embodiment, the pressing member 122 is a pressing brush, and the pressing member 122 is rotatably mounted on the front end of the drive bracket 121. The piston rod 1112 of the cylinder 111 is connected to the drive bracket 121 to drive the pressing member 122 to reciprocate in the direction of approaching / moving away from the box 400. Understandably, in some other embodiments, the pressing member 122 can also be a pressing roller or a pressing scraper. Similarly, when the box 400 moves in, the cooperation of the cylinder 111 and the drive bracket 121 allows the pressing roller or pressing scraper to contact the flip cover and side cover of the box 400 successively, and continuously provide pressing force to ensure the pressing movement of the tape at the flip cover and side cover.

[0028] In some embodiments, both the first clamping mechanism 10 and the second clamping mechanism 20 further include guide components, namely, the first clamping mechanism 10 includes a guide component 13, and the second clamping mechanism 20 includes a guide component 23. The driving component 11 and the driving component 12 respectively drive the clamping execution component 12 and the clamping execution component 22 to move along the guiding directions of the guide component 13 and the guide component 23, respectively, to reciprocate in a direction towards / away from the housing 400. In this invention, the guide component includes at least one guide member, such as... Figure 7 As shown, Figure 7 Taking the guide member 31 in the first pressing mechanism 10 as an example, the guide member 31 is connected to the fixed plate 30, and a groove 32 is formed on the guide member 31. The end of the drive bracket 121 passes through the groove 32 of the guide member 31 and moves within the groove 32 under the drive of the drive assembly 11. Based on the above design, the groove 32 guides the trajectory direction of the drive bracket 121 to avoid the drive bracket 121 from shaking.

[0029] In some embodiments, combined with Figure 8 As shown, the guide member 31 includes a mounting plate 312 and at least one roller assembly 311. Each roller assembly 311 includes two guide rollers 3111 arranged side by side on the mounting plate 312, with a groove 32 formed between the two guide rollers 3111. The mounting plate 312 is connected to the fixing plate 30, and the end of the drive bracket 121 passes through the groove 32. Further, a groove 3112 is formed inwardly at the center of the outer surface of each guide roller 3111.

[0030] Specifically, such as Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, in this embodiment, there are two guide members 31, which are arranged side by side at both ends of the cylinder 111 and connected to the cylinder barrel 1111 via a connecting plate 1113. Each guide member 31 also contains two mounting plates 312 and two roller assemblies 311, which are arranged side-by-side between the two mounting plates 312. The drive bracket 121 includes a connecting rod 1211 and two supports respectively connected to the rear ends of the connecting rod 1211. The rod 1212 and two fixing blocks 1213 extending forward from both ends of the connecting rod 1211 are respectively. The clamping member 122 is rotatably installed between the two fixing blocks 1213 via a rotating shaft 1214. The piston rod 1112 of the cylinder 111 is connected to the connecting rod 1211. The two support rods 1212 pass through the sliding grooves 32 of the two guide members 31 respectively. That is, each support rod 1212 passes through the sliding groove 32 of the two roller assemblies 311 in a guide member 31 in sequence and can move within the sliding groove 32.

[0031] When the tape pressing mechanism 100 of this utility model is in use, the box 400, which has been sealed and taped, moves in the direction of the arrow. First, the raised flip-top part contacts the pressing member 122 in the higher first pressing mechanism 10. Driven by the friction of the box 400 moving forward, the pressing member 122 in the first pressing mechanism 10 rotates and rolls and pre-tightens the tape on the flip-top, continuously providing pressing force to ensure the pressing movement of the tape at the flip-top. When the left side plate of the box 400 contacts the pressing roller of the second pressing mechanism 20, the first pressing mechanism 100... When the contact box 400 is at the junction of the flip cover and the right side panel, the pressing member 122 in the first pressing mechanism 10 and the pressing roller in the second pressing mechanism 20 are driven to move synchronously towards the box 400. That is, the pressing member 122 extends out to roll the tape on both sides of the box 400, pressing the tape at the junction of the flip cover and the side panel onto the side panel, achieving complete contact between the tape and the side panel, which greatly improves the bonding area and reliability of the side panel tape. After completion, the pressing member 122 moves backward to the initial position, and the box 400 continues to move forward.

[0032] In summary, the tape pressing mechanism 100 of this utility model achieves sequential and targeted pressing of the continuous bending area of ​​the flap-side panel. Compared with the existing scheme that only restricts the movement of the carton by contacting the moving carton with the guide rail fixed to the side of the conveyor belt, thereby guiding the carton to move along a preset trajectory and completing the tape sealing in the process, the tape pressing mechanism 100 of this embodiment can ensure that the tape is subjected to sufficient and uniform rolling pressure in all key areas, which greatly improves the reliability and area of ​​bonding, eliminates the need for manual labor, improves production efficiency, and reduces costs.

[0033] Understandably, this utility model can also provide a carton sealing machine, which includes a conveyor belt mechanism, a controller, and multiple tape pressing mechanisms 100 as described in the above embodiments. The conveyor belt mechanism includes a conveyor belt 200 and a motor for driving the conveyor belt 200 to move. This conveyor belt mechanism is a commonly used existing conveyor belt mechanism, which will not be described in detail here. In this utility model, multiple tape pressing mechanisms 100 are symmetrically arranged on both sides of the conveyor belt 200 along the forward direction of the carton 400. The controller is electrically connected to the tape pressing mechanism 100 and the motor of the conveyor belt mechanism to control the operation of the conveyor belt 200 and convey the carton or other carton 400. The tape pressing mechanisms 100 symmetrically arranged on both sides of the conveyor belt 200 can simultaneously and effectively press the tape on the flip-tops and side panels of the moving carton 400.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
