Description

Technical Field

[0001] The present invention relates to the field of packaging equipment, and particularly to an automatic cutting mechanism for packaging tail tape. Background Art

[0002] In the field of tire production and manufacturing, the film winding and packing of tires is a crucial step in the production process. After the tire completes the film winding and packing operation, there will inevitably be a section of tail tape left. This section of tail tape has no practical effect on the normal use of the tire and subsequent transportation and other links, and belongs to the redundant part. If it is not processed in time, it will not only affect the overall aesthetics of the tire, but may also cause a series of problems during subsequent handling and storage due to the entanglement of the tail tape, such as the tail tape winding around other objects resulting in tire displacement and damage, or the tail tape accidentally hooking the equipment causing production safety hazards.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0014] Refer to Figures 1 to 10 An automatic tail tape cutting mechanism for packaging as shown, including: A vacuum suction cup assembly 1, which adopts vacuum adsorption technology and can form an adsorption force to hold the tail tape 7 by connecting with a vacuum pumping device such as a vacuum pump A displacement assembly 2, the function of which is to drive the vacuum suction cup assembly 1 to move linearly so that it can accurately fit the tail tape 7 A cutting assembly 3, which is arranged adjacent to the vacuum suction cup assembly 1 and is used to cut off the tail tape 7 after the vacuum suction cup assembly 1 adsorbs the tail tape 7

[0016] In summary, the automatic tail tape cutting mechanism for packaging realizes the functions of automatic cutting and recycling of the tail tape 7 for tire packaging through the coordinated work of each component

[0017] As a preferred embodiment, a packaging tail band automatic cutting mechanism of the present invention further includes a lifting assembly 5 that drives the vacuum suction cup assembly 1 to move vertically, so that the height can be adjusted. The lifting assembly 5 is provided with a bracket 501, and sliders are provided on both sides of the bracket 501. A lifting rail 502 is installed on each of the two sliders. A horizontally arranged lifting fixed seat 503 is installed on the top of the two lifting rails 502. A lifting screw rod 504 and a servo motor 505 that drives the lifting screw rod 504 are installed on the top of the bracket 501. The top of the lifting screw rod 504 is connected to the lifting fixed seat 503, and the height of the lifting fixed seat 503 can be adjusted through the lifting screw rod 504.

[0018] As a preferred embodiment, the displacement assembly 2 of the present invention includes at least two sliders mounted on a lifting fixed seat 503, and a displacement slide rail 201 that slides with these sliders. A telescopic beam 202 is mounted on the displacement slide rail 201, and a telescopic cylinder 203 is also provided for driving the telescopic beam 202 to move linearly relative to the slider. Driven by the telescopic cylinder 203, the telescopic beam 202 can slide smoothly along the displacement slide rail 201, thereby realizing the linear movement of the vacuum suction cup assembly 1. This design enables the vacuum suction cup assembly 1 to accurately and quickly fit the tail tape 7, preparing for subsequent adsorption and cutting operations.

[0019] As a preferred embodiment, a positioning cylinder 6 is also installed on the lifting fixed seat 503, and at least one positioning top 601 is installed at the output end of the positioning cylinder 6. The positioning top 601 is located below the telescopic beam 202. When the telescopic beam 202 moves to a specified position, the positioning cylinder 6 can drive the positioning top 601 to be inserted into the telescopic beam 202 to position it, thereby ensuring the accuracy of the position.

[0020] As a preferred embodiment, the swing mechanism 4 includes a swing arm 401 and a swing cylinder 402. The swing arm 401 is axially connected to the telescopic beam 202. The vacuum suction cup assembly 1 is installed at one end of the swing arm 401. The swing cylinder 402 is connected to the other end of the swing arm 401. When the tail belt 7 is cut off, the swing cylinder 402 is started to drive the swing arm 401 to rotate around its axis, so that the vacuum suction cup assembly 1 swings to the specified position, and the cut tail belt 7 is loosened and falls into the recycling box or other specified recycling position. During the swinging process, the vacuum suction cup assembly 1 still maintains the adsorption force on the tail belt 7 to prevent the tail belt 7 from falling, thereby ensuring the smooth progress of the recycling work.

[0021] As a preferred embodiment, the vacuum suction cup assembly 1 of the present invention includes at least two telescopic shaft seats 101 fixed to the end of the swing arm 401 and telescopic shafts 102 installed in these telescopic shaft seats 101. A spring 103 is provided on the telescopic shaft 102. A thimble shaft mounting seat 104 is installed at the end of the telescopic shaft 102. A front and rear bracket 106 is fixed on the thimble shaft mounting seat 104. The front and rear bracket 106 extends forward and backward with respect to the thimble shaft mounting seat 104. A fixing plate 107 is pivotally connected to the thimble shaft mounting seat 104. At least two thimble shaft seats 108 are installed on the fixing plate 107. A thimble shaft 105 is installed on these thimble shaft seats 108. The tail end of the thimble shaft 105 has a joint 105a stuck in an inclined slot 106a provided at the rear end of the front and rear bracket 106. A vacuum suction cup body 109 is installed at the front end of the thimble shaft 105. A pull-down and plunge cylinder 1010 for driving the thimble shaft 105 to rotate around the pivot point so that the front end of the thimble shaft 105 retracts backward and moves downward is further provided on the thimble shaft mounting seat 104. It should be noted that among them, the main function of the telescopic shaft 102 is to enable the vacuum suction cup body 109 to abut against the tail tape 7, and by using the elastic action of the spring 103, the vacuum suction cup body 109 can stably adsorb the tail tape 7. After adsorption, the pull-down and plunge cylinder 1010 acts to drive the front end of the thimble shaft 105 to retract backward and move downward, separating the tail tape 7 from the product, creating favorable conditions for subsequent cutting operations, facilitating the cutting assembly 3 to more accurately complete the cutting work, and avoiding damaging the product during the cutting process.

[0022] As a preferred embodiment, the cutting assembly 3 of the present invention includes a blade 301 installed below the front end of the front and rear bracket 106 and a blade driving cylinder 302 for driving the blade 301 to move linearly to cut the tail tape 7. When the blade driving cylinder 302 is started, it will push the blade 301 to move linearly to cut the tail tape 7 at a certain speed, ensuring that the cut is neat and smooth, and avoiding the situation of residual tail tape 7 or incomplete cutting.

[0023] The working process of the present invention includes: First, the control system issues an instruction to the servo motor 505 of the lifting assembly 5 according to the specifications of the tire and the approximate height information of the tail tape 7. The servo motor 505 is started to drive the lifting lead screw 504 to rotate. Since the top of the lifting lead screw 504 is connected to the lifting fixed seat 503, as the lifting lead screw 504 rotates, the lifting fixed seat 503 will perform vertical movement along the lifting slide rails 502 on the sliders on both sides of the bracket 501. By precisely controlling the rotation direction and number of turns of the servo motor 505, the height of the lifting fixed seat 503 can be accurately adjusted, so that the vacuum suction cup assembly 1 installed on the subsequent structure reaches the appropriate height position to prepare for subsequent fitting of the tail tape 7.

[0024] When the vacuum suction cup assembly 1 reaches the appropriate height, the control system sends an action instruction to the telescopic cylinder 203 of the displacement assembly 2. The telescopic cylinder 203 starts and pushes the telescopic beam 202 installed on the displacement slide rail 201 to move linearly along the slider. The movement of the telescopic beam 202 drives the associated vacuum suction cup assembly 1 to move together. Under the stable drive of the telescopic cylinder 203, the telescopic beam 202 can accurately and quickly push the vacuum suction cup assembly 1 against the tail tape 7, enabling the vacuum suction cup assembly 1 to fully contact the tail tape 7 to ensure that the vacuum suction cup assembly 1 can hold the tail tape 7. Among them, the telescopic shaft 102 uses the elastic action of the spring 103 on it to enable the vacuum suction cup body 109 to adaptively press against the tail tape 7, ensuring full contact between the vacuum suction cup body 109 and the tail tape 7.

[0025] After the vacuum suction cup assembly 1 stably holds the tail tape 7, the control system sends an instruction to the pull-down and downward-probing cylinder 1010 on the thimble shaft mounting seat 104. The pull-down and downward-probing cylinder 1010 starts and drives the thimble shaft 105 to rotate around the pivot point. Since the end of the thimble shaft 105 has a joint 105a stuck in the inclined slot 106a provided at the rear end of the front and rear brackets 106, during the rotation process, the front end of the thimble shaft 105 will retract backward and move downward, thereby creating a certain distance between the tail tape 7 and the tire product. This action creates favorable space conditions for the subsequent cutting operation and avoids damaging the tire product during the cutting process.

[0026] After the tail tape 7 is pulled apart to the appropriate distance, the control system sends an instruction to the blade drive cylinder 302 of the cutting assembly 3. The blade drive cylinder 302 starts and pushes the blade 301 installed below the front end of the front and rear brackets 106 to move linearly, thus successfully completing the cutting of the tail tape 7.

[0027] After the tail tape 7 is cut, the control system sends an instruction to the swing cylinder 402 of the swing mechanism 4. The swing cylinder 402 starts and drives the swing arm 401 pivotally connected to the telescopic beam 202 to rotate around its pivot point. Since the vacuum suction cup assembly 1 is installed at one end of the swing arm 401, the rotation of the swing arm 401 will drive the vacuum suction cup assembly 1 to swing accordingly. During the swing process, the vacuum suction cup assembly 1 still maintains the adsorption force on the cut tail tape 7 to prevent the tail tape 7 from falling. When the swing arm 401 rotates to the designated recovery position, the control system stops the operation of the vacuum pump, the vacuum suction cup assembly 1 loses the adsorption force, and the cut tail tape 7 falls into the recovery box or other designated recovery positions, completing the recovery of the tail tape 7.
