Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging equipment, in particular to a glue shortage alarm device for a strip box gluing roller of a CT strip box packaging machine. Background Art

[0002] In the prior art, the strip box gluing mechanism of the CT strip box packaging machine refers to Figure 1 As shown, the CT carton packaging machine requires close cooperation between the glue cylinder 8, the glue roller 9, and the glue roller 10 to ensure the quality and quantity of glue applied to the carton, thereby ensuring the smooth subsequent packaging of the cigarette carton. The glue cylinder 8 is used to hold glue, the glue roller 8 is used to continuously remove glue from the glue cylinder 8 and continuously supply the removed glue to the glue roller 10, and the glue roller 10 is used to apply glue at the glue application position of the carton.

[0003] In actual production, due to reasons such as changing glue, equipment maintenance and cleaning, the glue cylinder 8 needs to be frequently disassembled and installed. In order to ensure the accurate installation of the glue cylinder 8, the existing technology has provided a rotary locking handle 7 and an in-position detection mechanism for detecting the position of the glue cylinder 8 on the glue cylinder 8. During the specific installation, it is only necessary to turn the rotary locking handle 7 into place to complete the accurate installation of the glue cylinder 8. However, in the actual production process, the rotary locking handle 7 often fails to rotate into place. At this time, the position of the glue cylinder 8 is less than 0.5mm out of place. The in-position detection is a travel switch, and its detection accuracy is difficult to achieve an accuracy of less than 0.5mm. Therefore, the glue cylinder 8 position detection mechanism does not alarm. However, if the glue cylinder 8 fails to be installed in place, the gap between the glue roller 9 and the glue coating roller 10 will exceed the glue amount of the glue roller 9. During the continuous production process, the glue roller 9 cannot stably and effectively provide glue to the glue coating roller 10, and the glue coating roller 10 cannot continuously and effectively adhere to the glue. Eventually, there will be insufficient glue application or direct lack of glue on the strip box, resulting in failure of cigarette strip box packaging, and more seriously, it will cause major quality accidents.

[0004] In order to solve the above problems, the present utility model is proposed. Utility Model Content

[0005] In order to solve the shortcomings of the existing technology, the purpose of the utility model is to provide a CT strip box packaging machine strip box gluing roller glue shortage alarm device, the alarm device mainly utilizes the connection or disconnection between the compressed air passage and the strip box suction negative pressure passage of the existing CT strip box packaging machine to realize the glue shortage alarm of the glue roller. The use of the utility model alarm device does not require major changes to the existing CT strip box packaging machine, and can effectively prevent cigarette box packaging quality problems caused by insufficient glue application or lack of glue.

[0006] The technical solution adopted in this utility model is:

[0007] The utility model provides a glue shortage alarm device for the glue coating roller of a CT strip box packaging machine. The CT strip box packaging machine is provided with a glue applying mechanism, which includes a glue cylinder 8, a glue roller 9 and a glue coating roller 10. The glue roller 9 is installed at the open end of the glue cylinder 8, and the glue coating roller 10 is installed obliquely above the glue roller 9. A rotary locking handle 7 is provided on the side wall of the glue cylinder 8. The alarm device includes:

[0008] Base 1, roller type control valve 2, one-way valve 3, stop rod 4, compressed air pipeline connecting pipe 51, valve inter-connecting pipe 52 and strip box adsorption negative pressure pipeline connecting pipe 53;

[0009] The base 1 is arranged below the rotary locking handle 7 and is installed on the wall panel of the CT strip box packaging machine. The roller-type control valve 2 and the one-way valve 3 are respectively fixed to the upper surface of the base 1; one end of the compressed air pipeline connecting pipe 51 is connected to the roller-type control valve 2, and the other end is connected to the compressed air passage of the external CT strip box packaging machine; one end of the strip box adsorption negative pressure pipeline connecting pipe 53 is connected to the one-way valve 3, and the other end is connected to the strip box suction negative pressure passage of the external CT strip box packaging machine; both ends of the valve inter-connecting pipe 52 are respectively connected to the non-connection ports of the roller-type control valve 2 and the one-way valve 3 to connect the roller-type control valve 2 and the one-way valve 3;

[0010] One end of the blocking rod 4 is connected to the rotary locking handle 7, and the other end is in movable contact with the valve 21 of the roller-type control valve 2. The blocking rod 4 is preferably positioned on the outer wall of the rotary locking handle 7, and its length should be at least sufficient to contact the valve switch of the roller-type control valve 2. The blocking rod 4 moves with the rotation of the rotary locking handle 7.

[0011] Preferably, the roller-type control valve 2 is located directly below the rotary locking handle 7 .

[0012] Preferably, the blocking rod 4 is a cylindrical bar welded to the rotary locking handle 7 .

[0013] Preferably, the air inlet end of the one-way valve 3 is connected to the roller-type control valve 2 through the inter-valve connecting pipe 52, and the air outlet end of the one-way valve 3 is connected to the strip box absorption negative pressure passage of the external CT strip box packaging machine through the strip box adsorption negative pressure pipeline connecting pipe 53.

[0014] Preferably, the base 1 is a rectangular oak block.

[0015] The utility model realizes the glue shortage alarm of the glue coating roller of the CT strip box packaging machine through the following principles:

[0016] When the rotary locking handle 7 is rotated to the right position, the position of the blocking rod 4 is just rotated with the rotary locking handle 7 to press the valve switch of the roller type control valve 2. At this time, the roller type control valve 2 is closed, the compressed air does not pass through, the compressed air passage is connected and the strip box suction negative pressure passage is disconnected, the strip box suction cup can normally absorb the strip box label paper, and the equipment can start normally;

[0017] When the rotary locking handle 7 is not rotated into place, the valve switch of the roller-type control valve 2 of the baffle rod 4 has no contact, or has contact but is not enough to close the roller-type control valve 2. The roller-type control valve 2 is in an open state, and the compressed air passes through the compressed air pipeline connecting pipe 51, the roller-type control valve 2, the valve inter-connecting pipe 52, the one-way valve 3 and the bar box adsorption negative pressure pipeline connecting pipe 53 in turn and finally enters the bar box absorption negative pressure passage. At this time, since the compressed air passage is connected to the negative pressure passage, the negative pressure in the negative pressure passage drops or disappears, resulting in the bar box suction cup being unable to absorb the bar box normally. The equipment sends a fault signal to shut down the equipment to remind the operator to check the equipment and troubleshoot. The equipment can only be restarted when the rotary locking handle 7 is rotated into place, thereby avoiding the quality accident of the bar box without glue due to the rotary locking handle 7 not being locked.

[0018] Beneficial effects of the utility model:

[0019] 1. The device has a simple structure, small size and compact structure. It cleverly connects the positive and negative pressure channels of the CT carton packaging machine through a control valve. When the rotary locking handle 7 is not in the correct position, the positive and negative pressure channels are connected, resulting in insufficient negative pressure in the carton suction cup, failure to suck the carton, and the device cannot start normally, so as to warn the operator to check the status of the equipment, effectively avoiding the problem of cigarette carton packaging failure.

[0020] 2. The utility model makes the installation of the roller-type control valve 2 and the one-way valve 3 more stable by arranging the roller-type control valve 2 and the one-way valve 3 on the base 1, and effectively ensures that the contact and disconnection operations of the blocking rod 4 and the roller-type control valve 2 are accurate and stable.

[0021] 3. The utility model utilizes the existing compressed air pipeline and the negative pressure pipeline adsorbed by the box, and makes the roller-type control valve 2, the one-way valve 3, the stop rod 4, and the ventilation pipes work together. It innovatively associates the installation position of the glue cylinder 8 with the connection or isolation between the compressed air passage and the negative pressure passage. The overall structure is simple and the cost is low. There is no need to rearrange or modify the existing equipment, and it can be promoted in batches.

Any modifications or improvements based on the teachings of the present invention fall within the scope of protection of the present invention. Where specific techniques or conditions are not specified in the examples, the techniques or conditions described in the literature in the field or in the product instructions shall be followed.

[0031] The utility model provides a CT strip box packaging machine strip box glue roller glue shortage alarm device, such as Figure 1 The CT strip box packaging machine is provided with a glue applying mechanism, which includes a glue cylinder 8, a glue roller 9 and a glue coating roller 10. The glue roller 9 is installed at the open end of the glue cylinder 8, and the glue coating roller 10 is installed obliquely above the glue roller 9. A rotary locking handle 7 is provided on the side wall of the glue cylinder 8. Figure 2 The alarm device shown includes:

[0032] Base 1, roller type control valve 2, one-way valve 3, stop rod 4, compressed air pipeline connecting pipe 51, valve inter-connecting pipe 52 and strip box adsorption negative pressure pipeline connecting pipe 53;

[0033] The base 1 is disposed below the rotary locking handle 7 and mounted on the wall panel of the CT strip packaging machine. The roller-type control valve 2 and the one-way valve 3 are respectively fixed to the upper surface of the base 1. The compressed air pipeline connecting pipe 51 is connected to the roller-type control valve 2 at one end and to the compressed air passage of the external CT strip packaging machine at the other end. The strip box adsorption negative pressure pipeline connecting pipe 53 is connected to the one-way valve 3 at one end and to the negative pressure suction passage of the external CT strip packaging machine at the other end. The valve connecting pipe 52 is connected to the roller-type control valve 2 and the one-way valve 3 at both ends to connect the roller-type control valve 2 and the one-way valve 3. The blocking rod 4 is connected to the rotary locking handle 7 at one end and is in movable contact with the valve 21 of the roller-type control valve 2 at the other end. The blocking rod 4 is disposed on the outer peripheral wall of the rotary locking handle 7 and is at least long enough to contact the valve switch of the roller-type control valve 2. The blocking rod 4 moves with the rotation of the rotary locking handle 7.

[0034] The specific structure and layout of the gluing mechanism can refer to the gluing mechanism in the CT box packaging machine in the prior art.

[0035] The roller-type control valve 2 is located directly below the rotary locking handle 7 , so that the rotary locking handle 7 can drive the blocking rod 4 to press the valve switch of the roller-type control valve 2 .

[0036] The blocking rod 4 is a cylindrical bar welded to the rotary locking handle 7 .

[0037] The air inlet end of the one-way valve 3 is connected to the roller-type control valve 2 through the valve inter-connecting pipe 52, and the air outlet end of the one-way valve 3 is connected to the strip box absorption negative pressure passage of the CT strip box packaging machine through the strip box adsorption negative pressure pipeline connecting pipe 53.

[0038] The base 1 is a rectangular oak block.

[0039] like Figure 3 As shown, when the rotary locking handle 7 is rotated into place, the position of the blocking rod 4 rotates with the rotary locking handle 7 to press the valve switch of the roller type control valve 2. At this time, the roller type control valve 2 is closed, the compressed air does not pass through, the compressed air passage is connected to the strip box suction negative pressure passage and cannot be connected. The strip box suction cup can normally absorb the strip box trademark paper, and the equipment can start normally.

[0040] like Figure 4As shown, when the rotary locking handle 7 is not rotated into place, the valve switch of the roller-type control valve 2 of the blocking rod 4 has no contact, or has contact but is not enough to close the roller-type control valve 2, and the roller-type control valve 2 is in the open state. The compressed air passes through the compressed air pipeline connecting pipe 51, the roller-type control valve 2, the valve inter-connecting pipe 52, the one-way valve 3 and the strip box adsorption negative pressure pipeline connecting pipe 53 in turn and finally enters the strip box absorption negative pressure passage. At this time, since the compressed air passage is connected to the negative pressure passage, the negative pressure in the negative pressure passage drops or disappears, causing the strip box suction cup to fail to absorb the strip box normally. The equipment sends a fault signal to shut down the equipment to remind the operator to check the equipment and troubleshoot, thereby avoiding the strip box no glue quality accident caused by the locking handle not being locked.
