Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a labeling machine adhesive scraping device. Background Technology

[0002] The function of a labeling machine is to automatically apply labels to the object to be labeled. A fully automatic linear adhesive labeling machine automatically applies cold glue to the label and then applies the label to the object to be labeled, which can achieve precise label application. In the beverage production process, labeling operations are also required. When applying cold glue to the label, a scraper is needed to scrape off excess glue to ensure that the glue layer is uniform and without accumulation. In the existing technology, the scraper of the labeling machine mainly consists of a scraper plate and a support frame. The scraper plate is installed on the labeling machine through the support frame. The existing adhesive scraping devices for labeling machines have the following shortcomings during use: 1. The angle of the scraper is fixed and cannot be adjusted according to usage needs. The smaller the angle of the scraper, the gentler the scraping force; the larger the angle, the stronger the scraping force. The fixed angle of the scraper cannot be used with adhesives of different viscosities, resulting in low flexibility of use; 2. Excess adhesive after scraping is usually collected by guiding it through the adhesive's own fluidity, which has low collection efficiency. In view of the above, this application proposes an adhesive scraping device for a labeling machine. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3A labeling machine adhesive scraping device includes a connecting seat 1. Both sides of the connecting seat 1 are integrally provided with L-shaped outer edges. The top of the L-shaped outer edges is provided with four bolt holes. The bolt holes cooperate with external bolts, so that the entire device can be installed in the required position of the labeling machine. A scraper 6 is provided below the connector 1, and it also includes: Mounting base 2 is located below connecting base 1 and between scraper plate 6, and a rotating groove 7 is provided at the bottom of mounting base 2; The vertical position adjustment mechanism 3 is installed between the top of the mounting base 2 and the bottom of the connecting base 1; The vertical position adjustment mechanism 3 includes an electric telescopic rod 301 fixedly connected to the bottom of the connecting seat 1. The bottom end of the output shaft of the electric telescopic rod 301 is fixedly connected to the top of the mounting seat 2. The electric telescopic rod 301 is used to adjust the vertical position of the mounting seat 2. Two guide rods 303 are fixedly connected to the bottom of the connecting seat 1. A guide tube 302 is slidably sleeved on the guide rod 303. A limit hole is opened on the right side of the guide tube 302. A limit block is fixedly connected to the bottom right side of the guide rod 303 and slidably connected to the corresponding limit hole. The limit block cooperates with the corresponding limit hole to limit and prevent the guide tube 302 from falling off. The bottom end of the guide tube 302 is fixedly connected to the top of the mounting seat 2. The guide rod 303 and the guide tube 302 cooperate to provide vertical guidance for the mounting seat 2. The rotating roller 5 is rotatably installed between the front inner wall and the rear inner wall of the rotating groove 7. The front inner wall and the rear inner wall of the rotating groove 7 are both fixedly connected to the first bearing. The front end and the rear end of the rotating roller 5 are both fixedly connected to the pin. The outer side of the pin is fixedly connected to the inner side of the corresponding first bearing inner ring. The pin and the first bearing cooperate to achieve the effect of rotating the rotating roller 5. The scraper 6 is fixedly installed at the bottom of the rotating roller 5. The outer side of the rotating roller 5 is bonded and covered with a hard rubber sleeve 8. The hard rubber sleeve 8 is in close contact with the inner wall of the rotating groove 7. The locking mechanism 9 is embedded and fixed on the left side of the mounting base 2 and squeezed into contact with the left side of the hard rubber sleeve 8; The locking mechanism 9 includes a rectangular tube 901 embedded and fixed to the bottom left side of the mounting base 2. The left side of the rectangular tube 901 is configured as a sealing structure. A pressure block 902 is slidably sleeved inside the rectangular tube 901. T-shaped slide rails are fixedly connected to the inner walls of the top and bottom of the rectangular tube 901. T-shaped grooves with openings on both sides are opened on the top and bottom of the pressure block 902. The T-shaped slide rails are slidably connected to the corresponding T-shaped grooves, and the T-shaped slide rails provide a lateral guiding effect for the pressure block 902. The right side of the pressure block 902 is configured as an arc-shaped structure and is fixedly connected to multiple pointed blocks 903. The tips of the pointed blocks 903 are pressed tightly against the left side of the hard rubber sleeve 8. The friction between the pointed blocks 903 and the hard rubber sleeve 8... Under the action of friction, the rotating roller 5 can be fixed. A screw 905 is fixedly connected to the left side of the pressure block 902. An internal threaded sleeve 904 is rotatably installed on the left inner wall of the rectangular tube 901. A bearing hole is opened on the left inner wall of the rectangular tube 901. A support bearing is fixedly fitted in the bearing hole. The inner side of the inner ring of the support bearing is fixedly connected to the outer side of the internal threaded sleeve 904. The support bearing serves to allow the internal threaded sleeve 904 to be rotatably installed. The internal threaded sleeve 904 is threaded onto the screw 905. The threaded connection allows the screw 905 to move laterally while the internal threaded sleeve 904 rotates. The left end of the internal threaded sleeve 904 extends to the left side of the rectangular tube 901 and is fixedly connected to a knob.

[0016] In this implementation scheme: When adjusting the tilt angle of the scraper 6 according to the viscosity of the adhesive, rotating the knob in the opposite direction drives the inner threaded sleeve 904 to rotate. While the inner threaded sleeve 904 rotates, it drives the screw 905 to move to the left. The screw 905 drives multiple pointed blocks 903 to separate from the hard rubber sleeve 8 through the pressure block 902, releasing the fixation of the rotating roller 5. At this time, the scraper 6 can be rotated to the left or right. While the scraper 6 rotates, its tilt angle changes. When the required angle is adjusted according to the viscosity of the adhesive, the rotation of the scraper 6 can be stopped. Then, rotating the knob in the forward direction causes the pressure block 902 to drive multiple pointed blocks 903 to move to the right and squeeze into contact with the left side of the hard rubber sleeve 8. Under the action of friction between the pointed blocks 903 and the hard rubber sleeve 8, the scraper 6 can be fixed after adjustment. After adjustment, the forward-opening electric telescopic rod 301 drives the mounting base 2 to move downward. The mounting base 2 drives the scraper 6 to move downward through the rotating roller 5 until it contacts the top of the label. When scraping the glue, the label moves and rubs against the scraper 6, and the excess glue is scraped off under the friction force.

[0017] It should be noted that the material of the scraper 6 is polyurethane, and its rotation angle can be determined by measuring with a ruler during adjustment. The specific measurement is existing technology and is well-known in the field, so it will not be elaborated here.

[0018] Furthermore: Reference Figure 2 A labeling machine's adhesive scraping device further includes an excess adhesive collection mechanism 4, which is installed on the right side of the mounting base 2 and the adhesive scraper 6. The excess adhesive collection mechanism 4 is used to collect adhesive. The excess glue collection mechanism 4 includes a support plate fixedly installed on the right side of the mounting base 2. A screw pump 402 is fixedly installed on the bottom right side of the support plate. The support plate supports the screw pump 402. A telescopic hose 403 is fixedly connected to the extraction end of the screw pump 402. A suction head 404 is fixedly connected to the left end of the telescopic hose 403. The telescopic hose 403 provides space for the suction head 404 to rotate. The suction head 404 is fixedly installed on the bottom right side of the scraper 6, with the top left side of the suction head 404 fixedly connected to the bottom right side of the scraper 6. A connecting block is provided to connect the suction tube head 404 and the scraper 6. A placement plate located above the screw pump 402 is fixedly connected to the right side of the support plate. A collection box 401 with an open top is placed on the top of the placement plate. The collection box 401 is used to collect glue. A guide pipe 405 is fixedly connected to the discharge end of the screw pump 402. The glue outlet of the guide pipe 405 extends into the collection box 401. The guide pipe 405 is used to guide the suctioned glue. The collection box 401 is placed directly on the placement plate, so that the collected glue can be directly removed and poured out later.

[0019] In this implementation plan: During the glue scraping process, the screw pump 402 is turned on. While the screw pump 402 is rotating, the excess glue scraped off is extracted sequentially through the telescopic hose 403 and the suction head 404. The extracted glue is directly introduced into the collection box 401 through the guide pipe 405. The collection box 401 collects the extracted glue. When the collection box 401 is full, the guide pipe 405 can be removed from the collection box 401, and the collection box 401 can be removed directly to pour out the glue.

[0020] It should be noted that the screw pump 402 is preferably an Alfa Laval SX series screw pump. The screw pump is a positive displacement pump that relies on the rotation and meshing of the screw rotor to transport liquids or high-viscosity media. Its specific transport principle is as follows: when the screw rotates, a low-pressure zone is formed at the suction end, and the glue is drawn into the pump chamber. The helical structure of the screw pushes the glue to move axially. The sealed chamber prevents backflow, and the glue is smoothly pushed to the outlet with stable pressure and no pulsation. Moreover, the screw pump has a wide viscosity range (1 cP-1,000,000 cP) and can handle glue containing trace impurities or air bubbles, which meets the needs of this field. In addition, its specific working principle is existing technology and will not be elaborated here. It should be noted that the guide tube 405 is made of hard plastic, and the outlet of the guide tube 405 is inclined towards the inside of the collection box 401.

[0021] Working principle: In use, the entire scraper device is fixed in the required position on the labeling machine via the connecting seat 1. After fixing, the tilt angle of the scraper blade 6 is first adjusted according to the viscosity of the adhesive. During adjustment, the knob is rotated in the opposite direction to drive the internal threaded sleeve 904 to rotate. While the internal threaded sleeve 904 rotates, it drives the screw 905 to move to the left. The screw 905 drives the pressure block 902 to move to the left. The pressure block 902 drives multiple pointed blocks 903 to separate from the hard rubber sleeve 8, releasing the fixation of the rotating roller 5. At this time, the scraper blade 6 can be rotated to the left or right. The scraper blade 6 drives the rotating roller 5 to rotate. At the same time, the rotation of the scraper blade 6 also drives the suction tube head 404 to rotate via the connecting block. As the scraper blade 6 rotates, its tilt angle changes. When the required angle is adjusted according to the viscosity of the glue, the rotation of the scraper blade 6 can be stopped. Then, the knob is rotated in the forward direction to drive the internal threaded sleeve 904 to rotate. As the internal threaded sleeve 904 rotates, it drives the screw 905 to move to the right. The screw 905 drives multiple pointed blocks 903 to move to the right through the clamping block 902 until they are pressed into contact with the left side of the hard rubber sleeve 8. Under the action of friction between the pointed blocks 903 and the hard rubber sleeve 8, the scraper blade 6 can be fixed after adjustment. The adjustable tilt angle of the scraper blade 6 makes it suitable for different scraping needs and improves the flexibility of use. After adjustment, the forward-opening electric telescopic rod 301 drives the mounting base 2 to move downward. The mounting base 2 drives the two guide tubes 302 to slide downward on the corresponding guide rods 303 to perform vertical guidance. The mounting base 2 drives the scraper 6 to move downward to contact the top of the label through the rotating roller 5. When scraping the glue, the label moves and rubs against the scraper 6. Under the friction, the excess glue is scraped off. The excess glue is concentrated on the right side of the scraper 6. Its scraping principle is the same as the scraping principle in the prior art, and will not be described in detail here. During the glue scraping process, the screw pump 402 is turned on. As the screw pump 402 rotates, it sequentially extracts the scraped excess glue through the telescopic hose 403 and the suction head 404. The extracted glue enters the collection box 401 directly through the guide pipe 405. The collection box 401 collects the extracted glue. Compared with the existing technology that uses the fluidity of the glue itself for diversion and collection, the method of collecting excess glue by suction from the screw pump 402 significantly improves the collection efficiency.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
