Description

Technical Field

[0001] This utility model relates to the field of carton sealing machine technology, and in particular to a carton sealing machine anti-jamming device. Background Technology

[0002] A carton sealing machine is a device used to seal cartons and apply tape. In practical applications, carton sealing machines are placed on production lines, and cartons with sealing functions pass through the machine sequentially to achieve the desired seal. In existing technologies, cartons inevitably experience some degree of swaying during transport on the production line, leading to sealing failures, and in some cases, even jamming, necessitating machine shutdown and severely disrupting normal production. In view of these technical problems, this application proposes an anti-jamming device for carton sealing machines, enabling the machine to guide the cartons during the sealing process, preventing jamming and ensuring normal production. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a carton sealing machine anti-jamming device, which aims to solve the technical problem that the carton sealing machine cannot guide the carton during the sealing process and is prone to jamming.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A box sealing machine anti-jamming device includes a frame with two pressure rods arranged opposite each other on the frame. In the vertical direction, each pressure rod is arranged with its front end facing upward and its rear end facing downward. In the horizontal projection, each pressure rod is arranged with its front end facing outward and its rear end facing inward. Auxiliary pressure rollers are arranged on both sides of the frame, and the axis of each auxiliary pressure roller is parallel to the vertical direction.

[0006] Furthermore, in the anti-jamming device of the sealing machine, two first support rods are provided at the front end of the two pressure rods on the frame, and the front end of each pressure rod is connected to the corresponding first support rod.

[0007] Furthermore, in the anti-jamming device of the sealing machine, two positioning blocks are provided at the rear end of the two pressure rods on the frame, and the rear end of each pressure rod is connected to the corresponding positioning block.

[0008] Furthermore, in the anti-jamming device of the sealing machine, each pressure rod has a bent end at its rear end, and each end is connected to the corresponding positioning block.

[0009] Furthermore, in the anti-jamming device of the sealing machine, two second support rods are provided on the frame, and each auxiliary pressure roller is set on the corresponding second support rod.

[0010] Furthermore, in the anti-jamming device of the sealing machine, each second support rod includes a vertical arm and a horizontal arm at the bottom of the vertical arm, and each auxiliary pressure roller is set on the horizontal arm of the corresponding second support rod.

[0011] Furthermore, in the anti-jamming device of the sealing machine, each horizontal arm is provided with two or more auxiliary pressure rollers; the number of auxiliary pressure rollers provided on each horizontal arm is equal and the specifications are the same.

[0012] Furthermore, in the anti-jamming device of the sealing machine, the auxiliary pressure roller is located near the bottom end of the pressure rod and away from the top end of the pressure rod.

[0013] Beneficial effects: This utility model provides an anti-jamming device for a carton sealing machine. Compared with the prior art, auxiliary pressure rollers are set on both sides of the frame, with their axes parallel to the vertical direction, which can play a precise guiding role during carton transport. These auxiliary pressure rollers can limit the swaying of the carton on the production line, ensuring that the carton always moves on the predetermined path, greatly reducing the risk of carton jamming and ensuring the continuity of production.

[0022] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0023] Please see Figure 1 and Figure 2This utility model provides a box-sealing machine anti-jamming device. The accompanying drawings are only simplified structural diagrams used to explain the structural principle and are not proportional to the actual product. The drawings only show structures relevant to the present utility model; some conventional structures are not specifically depicted. The terms "first," "second," etc., used herein are merely different names for similar structures for ease of explanation and are not intended to limit this application. Figure 1 The direction of the middle arrow indicates the direction of the carton's transport.

[0024] For ease of understanding, Figure 1 The drawing shows four states of cardboard boxes: 91, 92, 93, and 94.

[0025] The aforementioned anti-jamming device for a carton sealing machine includes a frame 1, on which two pressure rods 2 are arranged opposite each other. Vertically, each pressure rod is positioned with its front end facing upwards and its rear end facing downwards; horizontally, each pressure rod is positioned with its front end facing outwards and its rear end facing inwards. Auxiliary pressure rollers 3 are respectively arranged on both sides of the frame, with the axis of each auxiliary pressure roller parallel to the vertical direction. Figure 1 In the middle, the front end of the compression rod is the left end, and the rear end of the compression rod is the right end.

[0026] Before sealing the carton, the "main face" 901 (or "large face") on the top of the carton is in an open state. Figure 2 The state shown by the dashed line 901). The aforementioned pressure bar, with its front higher than its rear, can gradually lower the main box surface until it is closed. Figure 2 (As shown by the solid line 901'), this facilitates the application of tape for sealing the box. The tape application mechanism is existing technology in box sealing machines and is not the inventive point of this application, therefore it will not be specifically drawn.

[0027] From the appendix Figure 2 It can be observed that the auxiliary pressure rollers 3 on both sides of the frame are also located on both sides of the carton, and the auxiliary pressure rollers can rotate around the vertical axis, thereby playing a guiding role in the carton conveying process. The carton is always located inside the auxiliary pressure rollers during the entire sealing process, avoiding large displacement of the carton on the conveyor belt of the production line, thus avoiding carton jamming.

[0028] Furthermore, two first support rods 41 are provided at the front end of the two pressure rods 2 on the frame, and the front end of each pressure rod is connected to the corresponding first support rod (preferably by bolts). This arrangement facilitates the assembly and disassembly of the pressure rods.

[0029] Furthermore, two positioning blocks 43 are provided at the rear ends of the two pressure rods 2 on the frame, and the rear end of each pressure rod is connected to the corresponding positioning block. By setting the positioning blocks, it is easy to support the rear end of the pressure rod and prevent the pressure rod from deforming.

[0030] Furthermore, each pressure bar 2 has an upward-bent end 21 at its rear end, and each end 21 is connected to the corresponding positioning block 43. By setting the bent end, the pressure bars can be connected, and the top of the carton can be smoothly transitioned as it passes over the bottom of the pressure bar, avoiding scratches on the carton.

[0031] Furthermore, the frame is equipped with two second support rods, and each auxiliary pressure roller is mounted on its corresponding second support rod. The second support rods are detachably connected to the frame, allowing for easy assembly and disassembly of the auxiliary pressure rollers.

[0032] Furthermore, each second support rod includes a vertical arm 421 and a horizontal arm 422 located at the bottom of the vertical arm, with each auxiliary pressure roller 3 mounted on the corresponding horizontal arm 422 of the second support rod. By providing the horizontal arm, multiple auxiliary pressure rollers 3 can be mounted on the same side.

[0033] Furthermore, each cross arm is equipped with two or more auxiliary pressure rollers 3 ( Figure 1 The diagram schematically shows three auxiliary pressure rollers; the number and specifications of the auxiliary pressure rollers on each crossarm are equal. This arrangement ensures that each section has multiple auxiliary pressure rollers guiding the carton, and the number of pressure rollers on both sides is the same. The pressure rollers on both sides of the carton restrict the overall force balance, thus improving the guiding effect.

[0034] like Figure 1 As shown, the auxiliary pressure roller is further positioned near the bottom of the pressure bar and away from its top. This arrangement brings the auxiliary pressure roller closer to the sealing station, ensuring that the carton is less likely to wobble during the sealing process.

[0035] As can be seen from the above analysis, by setting auxiliary pressure rollers on the left and right sides respectively, this application can guide the cartons during the conveying process on the production line, avoid swaying and carton jamming, and ensure normal production.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present utility model.
