[0002] The carton sealing machine is mainly suitable for carton sealing packaging, and needs to accurately position the carton during the working process to ensure that the carton is sealed intact.

[0003] In order to facilitate the conveying of the carton, the carton positioning structure generally uses side guide wheels for auxiliary positioning. For example, a carton positioning mechanism of a carton sealing machine disclosed in Chinese Patent No. CN211253216U discloses two groups of side positioning mechanisms spaced on the bearing frame to form a passage for the carton to pass through. The side positioning mechanism includes a fixed block, the fixed block is rotatably mounted with a side guide wheel, the top surface of the fixed block is sequentially provided with a connecting block, a movable block and a clamping bolt from bottom to top, the movable block is slidably sleeved on the bearing frame and locked by the clamping bolt.

[0004] In summary, the existing carton positioning guide wheel is slidably sleeved on the bearing frame through the movable block, and a connecting hole is formed in the movable block. The clamping bolt passes through the connecting hole and abuts against the bearing frame. The clamping bolt is used to fix the movable block on the bearing frame to realize the adjustment and installation of the positioning guide wheel. However, when the movable block on the bearing frame needs to be added or removed subsequently, the bearing frame needs to be completely disassembled to realize the addition or removal of the movable block, which causes inconvenience in adding the positioning guide wheel, and the fixed connection between the movable block and the bearing frame is only through the clamping bolt which is tightly abutted on the bearing frame along the thread, which easily causes small friction due to the small contact surface between the clamping bolt and the bearing frame, resulting in insufficient connection strength and loosening of the positioning guide wheel.

[0005] Therefore, it is necessary to provide a machine frame guide wheel set structure for carton sealing machine to improve the above problems. UTILITY MODEL CONTENTS

[0006] In view of the defects of the existing technology, the technical problem to be solved by the utility model is to provide a machine frame guide wheel set structure for carton sealing machine.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 4 The present invention preferably provides a frame guide wheel assembly structure for a carton sealing machine, including a frame 1 and side guide wheel assemblies symmetrically arranged on both sides of the frame 1. The side guide wheel assembly includes a slide 2, a clamping plate 3, a knob 4, and guide wheels 5. The guide wheels 5 are rotatably mounted on the slide 2. The frame 1 has a guide groove 6. The slide 2 has two guide posts 7 spaced apart. The slide 2 is mounted on the upper side of the frame 1, and the two guide posts 7 are movably mounted in the guide groove 6. The clamping plate 3 is located below the frame 1, and the knob 4 is located above the slide 2. A screw 81 is provided on the clamping plate 3 within the guide groove 6. The slide 2 has a through hole 82. The upper part of the screw 81 passes through the through hole 82 and is threadedly connected to the knob 4. The clamping plate 3 has two limiting holes 83 spaced apart, and the two guide posts 7 are correspondingly mounted in the two limiting holes 83.

[0021] Specifically, the slide table is attached to the machine frame, and the two guide posts on the slide table are movable with the guide slots of the machine frame. This allows the guide rollers to move and adjust along the length of the guide slots as the slide table moves. Rotating the knob causes the two limiting holes of the clamping plate to engage with the two guide posts of the slide table, allowing the clamping plate to move up and down relative to the slide table. When the user turns the knob, the knob moves along the screw thread of the clamping plate, forcing the knob and the clamping plate to move closer together, thus clamping the clamping plate. The sliding table is clamped to the machine frame, thus achieving a fixed connection between the sliding table and the machine frame. Conversely, turning the knob in the opposite direction moves the knob and the clamping plate away from each other, loosening the clamping of the sliding table and the machine frame. The clamping contact between the knob and the clamping plate increases the contact area and thus increases the friction, making the connection between the sliding table and the machine frame more secure. The sliding table rests on the machine frame. When the knob is completely released and disengaged from the screw, the sliding table and the clamping plate can be disassembled and detached from the machine frame, thus facilitating the disassembly of the guide wheel assembly and subsequent installation.

[0022] Further, the screw rod 81 is a fastening screw which is threaded through the clamping piece 3 and the screw end of the fastening screw abuts the lower side of the clamping piece 3.

[0023] Further, the guide column 7 is threaded through the sliding table 2. Specifically, the guide column can be a connecting screw which is inserted into the limiting hole of the clamping piece through the end of the connecting screw to achieve the up and down limiting movement of the clamping piece relative to the sliding table, and the connecting screw is a commercially available accessory, thereby effectively reducing the cost of mold production.

[0024] Further, the knob 4 is provided with anti-skid lines along the circumferential outer wall to facilitate the user to rotate the knob.

[0025] Further, the machine frame 1 comprises a ring-shaped rectangular frame 11 and a pressing plate 12 connected to the middle part of the ring-shaped rectangular frame 11, the guide slot 6 is formed on the ring-shaped rectangular frame 11, and the guide inclined plate 13 is arranged on one side of the pressing plate 12 close to the side guide wheel set. Specifically, the pressing plate cooperates with the guide inclined plate to abut and press the upper cover plate of the carton, thereby facilitating the carton packaging.

[0026] Further, the machine frame 1 is symmetrically provided with a connecting shaft sleeve 14 on both sides, and the inner cavity of the connecting shaft sleeve 14 is provided with an internal thread. Further, the machine frame is installed on the externally vertically arranged screw rod, thereby achieving the height adjustment and installation of the machine frame and the guide wheel.
