Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated case sealing technical field, concretely is a kind of sealing equipment of corrugated case. BACKGROUND

[0002] Corrugated case is usually used to package various articles, when the article is packaged, in order to prevent the article from falling out of the paper box, usually need to be sealed by sealing equipment with tape.

[0003] The sealing equipment commonly used at present is a tape dispenser, which is a tool for quickly cutting and dispensing tape, widely used in packaging, office, logistics, home and other fields. It can help users use tape efficiently and neatly, reduce waste and improve work efficiency.

[0004] But the tape dispenser used at present can only adapt to the same size tape, the applicable range is narrow, and there is no function of limiting the tape roll, so that the tape roll may be inclined during sealing, resulting in poor tape fitting effect, therefore we propose a kind of sealing equipment of corrugated case. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a kind of sealing equipment of corrugated case to solve the problems raised in the above background.

[0006] To achieve the above object, the utility model provides the following technical scheme: a kind of sealing equipment of corrugated case, including tape dispenser, the tape dispenser is composed of cover plate, tape roll placing rack, cutter, guide roller and sticking roller, tape roll is placed on the tape roll placing rack, limiting mechanism is arranged on the tape roll placing rack;

[0007] The limiting mechanism includes:

[0008] Control block, control block is used to move by connecting rod control ring;

[0009] Stretching spring, stretching spring is used to drive control block to reset when control block is not stressed;

[0010] Resisting block, resisting block is used to limit tape roll;

[0011] Limiting piece, limiting piece is used to limit resisting block;

[0012] Supporting block, supporting block is used to support resisting block;

[0013] The inner side of supporting block and tape roll placing rack is provided with driven assembly for controlling the overturning and resetting of resisting block.

[0014] Preferably, the control block and the ring are slidably mounted on the inner side of the tape roll placement rack. The control block and the ring are fixed together by a connecting rod. A tension spring is fixed to the side of the control block away from the connecting rod. The end of the tension spring away from the control block is fixed to the inner side of the tape roll placement rack. The support block is fixed to the side of the ring away from the connecting rod. An abutment block is provided on the outer wall of the support block. The limiting member is provided on the support block and the abutment block. By pushing the control block, the control block moves with the connecting rod and the ring. The ring can then move with the abutment block and the support block, allowing the distance between the abutment block and the side wall of the tape roll placement rack to be adjusted, so that tape rolls of different sizes can be placed. After the tape rolls are placed, simply release the control block. The control block will return to its original position under the action of the tension spring and the connecting rod, and the ring will return to its original position with the abutment block. The abutment block can then cooperate with the side wall of the tape roll placement rack to fix the tape roll, ensuring that the tape roll will not be skewed during the sealing process, thus avoiding affecting the tape's adhesion effect.

[0015] Preferably, the limiting member includes a rod that passes through the contact block and is slidably connected to it. A fixing block is fixed to the end of the rod away from the support block. A return spring is fixed to the side of the fixing block near the rod. The end of the return spring away from the fixing block is fixed to the contact block. An insertion hole is provided on the side of the support block near the contact block. The rod is inserted into the insertion hole to limit the contact block and ensure that the contact block can stably limit the contact of the tape roll.

[0016] Preferably, the tape roll placement rack has a groove through which the abutment block can pass and move.

[0017] Preferably, the driven component includes an L-shaped push rod, which is fixed to the inner side of the tape roll holder. A groove is formed on the side of the support block near the contact block. A rotating rod is rotatably mounted on the inner side of the groove in the support block. The rotating rod passes through the contact block and is fixed to it. A spiral spring is fixed to the outer wall of the rotating rod, and the end of the spiral spring away from the rotating rod is fixed in the groove of the support block. An L-shaped contact rod is fixed to the outer wall of the L-shaped push rod. When the tape roll needs to be removed, simply push the control block to move the connecting rod and the ring. The ring will then move the support block and the contact block. When the L-shaped contact rod abuts against the inclined surface of the fixed block, it pushes the fixed block and the insert rod away from the support block. The movement allows the insert to retract from the socket, releasing the restraint on the contact block. As the ring continues to move with the contact block, the L-shaped push rod abuts against the contact block, pushing it to rotate at the position where the rotating rod and support block connect, thus deflecting the contact block. At this point, the tape can be unwound. After releasing the control block, as it resets with the connecting rod and ring under the action of the tension spring, the contact block is no longer abutted by the L-shaped push rod, and the fixing block is no longer pushed by the L-shaped contact rod. Under the action of the spiral spring, the rotating rod rotates with the contact block to reset. When the insert follows the contact block to the position of the socket, the insert inserts into the socket under the action of the reset spring, thus re-limiting the contact block. This method is convenient to use.

[0018] Compared with the prior art, this utility model provides a sealing device for corrugated cardboard boxes, which has the following advantages:

[0019] 1. The sealing equipment for this corrugated cardboard box, through a limiting mechanism, allows for the movement of the control block, which in turn moves the connecting rod and the ring. The ring then moves the abutment block and the support block, allowing the abutment block to adjust the distance between itself and the side wall of the tape roll placement rack. This enables the placement of tape rolls of different sizes. After the tape rolls are placed, simply releasing the control block allows it to return to its original position via the connecting rod and the tension spring. The ring then moves the abutment block back to its original position, and the abutment block, in turn, engages with the side wall of the tape roll placement rack to secure the tape rolls. This ensures that the tape rolls do not become skewed during the sealing process, preventing any impact on the tape's adhesion.

[0020] 2. This corrugated cardboard box sealing equipment, through its limiting mechanism and driven components, allows for easy removal of the tape roll when the tape needs to be unwound. Simply push the control block to move the connecting rod and ring, which in turn moves the support block and the abutment block. When the L-shaped abutment rod abuts against the inclined surface of the fixed block, it pushes the fixed block and the insertion rod to move away from the support block. The insertion rod interface then exits from the insertion hole, releasing the restriction on the abutment block. As the ring continues to move with the abutment block, the L-shaped push rod abuts against the abutment block, pushing it to rotate at the position where the rotating rod and support block connect, thus deflecting the abutment block. At this point, the tape roll can be unwound and replaced, making it convenient to use. Attached Figure Description

[0028] like Figures 1-6 As shown, this utility model provides a technical solution: a sealing device for corrugated cardboard boxes, including a tape dispenser 1. The tape dispenser 1 consists of a cover plate 11, a tape roll placement rack 12, a cutter 13, a guide roller 14, and a bonding roller 15. A tape roll 4 is placed on the tape roll placement rack 12. A limiting mechanism 2 is provided on the tape roll placement rack 12. The limiting mechanism 2 includes: a control block 21, a connecting rod 22, a ring 23, a tension spring 24, an abutment block 25, a limiting member 26, and a support block 27. A driven component 3 for controlling the flipping and resetting of the abutment block 25 is provided on the inner side of the support block 27 and the tape roll placement rack 12.

[0029] Control block 21 and ring 23 are slidably mounted on the inner side of tape roll holder 12. Control block 21 and ring 23 are fixed together by connecting rod 22. A tension spring 24 is fixed on the side of control block 21 away from connecting rod 22. The end of tension spring 24 away from control block 21 is fixed on the inner side of tape roll holder 12. Support block 27 is fixed on the side of ring 23 away from connecting rod 22. A stop block 25 is provided on the outer wall of support block 27. Limiting member 26 is provided on support block 27 and stop block 25. By pushing control block 21, control block 21 moves with connecting rod 22 and ring 23. 3 can move the contact block 25 and support block 27, so that the distance between the contact block 25 and the side wall of the tape roll placement rack 12 can be adjusted, so that tape rolls 4 of different sizes can be placed. After the tape roll 4 is placed, simply release the control block 21. The control block 21 will be reset by the linkage 22 under the action of the tension spring 24, and the ring 23 will be reset by the ring 23. The contact block 25 will be reset, and the contact block 25 can be fixed to the tape roll 4 with the side wall of the tape roll placement rack 12, so that the tape roll 4 will not be skewed during the sealing process, and the tape bonding effect will not be affected.

[0030] The limiting component 26 includes a rod 261 that passes through and slidably connects to the contact block 25. A fixing block 262 is fixed to the end of the rod 261 away from the support block 27. A return spring 263 is fixed to the side of the fixing block 262 near the rod 261. The end of the return spring 263 away from the fixing block 262 is fixed to the contact block 25. An insertion hole 264 is provided on the side of the support block 27 near the contact block 25. The rod 261 is inserted into the insertion hole 264 to limit the contact block 25, ensuring that the contact block 25 can stably resist and limit the tape roll 4. A sliding groove 5 is provided on the tape roll holder 12, through which the contact block 25 can pass and move.

[0031] The driven component 3 includes an L-shaped push rod 31, which is fixed to the inside of the tape roll holder 12. A groove is provided on the side of the support block 27 near the contact block 25. A rotating rod 32 is rotatably mounted on the inside of the groove of the support block 27, passing through and being fixed to the contact block 25. A spiral spring 33 is fixed to the outer wall of the rotating rod 32, with the end of the spiral spring 33 away from the rotating rod 32 fixed in the groove of the support block 27. An L-shaped contact rod 34 is fixed to the outer wall of the L-shaped push rod 31. When the tape roll 4 needs to be removed, simply push the control block 21 to move the connecting rod 22 and the ring 23. The ring 23 will then move the support block 27 and the contact block 25. When the L-shaped contact rod 34 abuts against the inclined surface of the fixing block 262, it pushes the fixing block 262 and the insertion rod 261 to move away from the support block 27. The insertion rod 261 interface is located at the insertion hole 2. Withdrawal within 64 releases the restriction on the contact block 25. As the ring 23 continues to move with the contact block 25, the L-shaped push rod 31 abuts against the contact block 25, pushing the contact block 25 to rotate at the position where the rotating rod 32 and the support block 27 are connected, thus deflecting the contact block 25. At this point, the tape roll 4 can be removed. After releasing the control block 21, when the control block 21 returns to its original position with the connecting rod 22 and the ring 23 under the action of the tension spring 24, the contact block 25 is no longer abutted by the L-shaped push rod 31, and the fixing block 262 is no longer pushed by the L-shaped contact rod 34. Under the action of the spiral spring 33, the rotating rod 32 rotates with the contact block 25 to return to its original position. When the insertion rod 261 follows the contact block 25 to the position of the insertion hole 264, under the action of the return spring 263, the insertion rod 261 is inserted into the insertion hole 264, thus re-limiting the contact block 25, making it convenient to use.

[0032] In this invention, during use, the control block 21 is first pushed to move the connecting rod 22 and the ring 23. When the L-shaped abutment rod 34 abuts against the inclined surface of the fixed block 262, it pushes the fixed block 262 and the insertion rod 261 to move away from the support block 27. The insertion rod 261 interface exits from the insertion hole 264, thus releasing the restriction on the abutment block 25. As the ring 23 continues to move with the abutment block 25, the L-shaped push rod 31 abuts against the abutment block 25, pushing the abutment block 25 to rotate at the position where the rotating rod 32 and the support block 27 are connected, thus deflecting the abutment block 25. Place the tape roll 4 on the tape roll holder 12, release the control block 21, and when the control block 21 returns to its original position along with the connecting rod 22 and the ring 23 under the action of the tension spring 24, the abutment block 25 is no longer abutted by the L-shaped push rod 31, and the fixing block 262 is no longer pushed by the L-shaped abutment rod 34. Under the action of the spiral spring 33, the rotating rod 32 rotates and returns to its original position along with the abutment block 25. When the insertion rod 261 rotates with the abutment block 25 to the position of the insertion hole 264, under the action of the return spring 263, the insertion rod 261 is inserted into the insertion hole 264, thereby re-limiting the abutment block 25.

[0033] At the same time, the contact block 25 can cooperate with the side wall of the tape roll holder 12 to fix the tape roll 4, ensuring that the tape roll 4 will not be skewed during the sealing process, thus avoiding affecting the adhesion effect of the tape.

[0034] When sealing a corrugated carton, the tape roll 4 is passed around the guide roller 14 and the bonding roller 15. The bonding roller 15 is aligned with the moving tape dispenser 1 of the corrugated carton, and the tape is then bonded to the corrugated carton to achieve the sealing operation. The tape is then cut by the cutter 13 to complete the sealing.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
