Description

Technical Field

[0001] This utility model belongs to the technical field of labeling machine equipment, and specifically relates to a label guiding device for a labeling machine. Background Technology

[0002] Labeling is the process of affixing labels to the outside of a product. The information on the label typically includes basic information such as the product name, weight, volume, and purpose, making it easier for consumers and users to find and locate their desired product. A labeling machine is a device that affixes rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. When a label is affixed to a packaging container, if the deviation of the label's center line from its theoretical position is within a specified range, it is called a correct label. If multiple labels are on the same packaging container, the deviation of each label from its theoretical position should be calculated according to the above definition, and all deviations should be within the specified range.

[0003] In existing labeling machines, only guide rollers are used to guide the label tape during use. The angle of the label tape cannot be limited, which makes it easy for the label tape to deviate during labeling, thus affecting the labeling effect. Moreover, after long-term use, the guide rollers are in constant contact with the label tape and are prone to wear, requiring regular replacement. The lack of a structure for quick disassembly and assembly of the guide rollers reduces work efficiency.

[0004] Therefore, a label guiding device for labeling machines is needed to solve the problems in existing technologies, such as the inability to limit the angle of the label tape, which leads to the label tape easily shifting during labeling, and the lack of a structure for quick assembly and disassembly of the guide roller, which reduces work efficiency.

[0023] Please see Figure 1-4 This utility model provides a label guiding device for a labeling machine, including a mounting plate 1, a guiding mechanism 2, a pressure roller 3, a baffle 4, a sponge roller 5, a fixed roller 6, and a take-up roller 7. The guiding mechanism 2 is located above the mounting plate 1, the pressure roller 3 is located in front of the guiding mechanism 2, the baffle 4 is located to the left of the pressure roller 3, and the baffle 4 is rotatably connected to the top of the mounting plate 1. The sponge roller 5 is located to the left of the mounting plate 1, the fixed roller 6 is located to the left of the sponge roller 5, and the take-up roller 7 is located to the left of the fixed roller 6.

[0024] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the guide mechanism 2 consists of a base plate 201, a support plate 202, an adjustment mechanism 203, a bearing 204, a connecting shaft 205, a disassembly and assembly mechanism 206, a guide roller 207, a limit ring 208, a label detection head 209, and a scale line 210. The base plate 201 is fixedly connected to the upper and lower sides of the support plate 202 by bolts. The adjustment mechanism 203 is located inside the base plate 201. The bearing 204 is located inside the base plate 201. The connecting shaft 205 is fixedly connected to the outside of the bearing 204. The disassembly and assembly mechanism 206 is located between the guide roller 207 and the connecting shaft 205.

[0025] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the adjusting mechanism 203 consists of a lead screw 2032, a cross block 2033, a driving bevel gear 2034, a driven bevel gear 2035, a fixed shaft 2036, a handle 2037, a connecting plate 2038, and a pointer 2039. The support plate 202 has symmetrical cross slots 2031 on its upper and lower sides. The lead screw 2032 is rotatably connected to the inside of the cross slot 2031, and the cross block 2033 is threaded to the outside of the lead screw 2032 and slidably connected to the inside of the cross slot 2031.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the driving bevel gear 2034 is fixedly connected to the outside of the top surface of the lead screw 2032, the driven bevel gear 2035 is located above the driving bevel gear 2034, and the driven bevel gear 2035 meshes with the driving bevel gear 2034. The fixed shaft 2036 is rotatably connected to the side of the support plate 202, and the left end of the fixed shaft 2036 is fixedly connected to the driven bevel gear 2035. The handle 2037 is fixedly connected to the right end of the fixed shaft 2036. The connecting plate 2038 is fixedly connected to one side of the cross block 2033. The pointer 2039 is symmetrically fixedly connected to the front and rear sides of the connecting plate 2038. The scale line 210 is symmetrically arranged on the front and rear sides of the support plate 202, and the pointer 2039 points to the scale line 210.

[0027] By setting the pointer 2039 and the scale line 210, the position of the limiting ring 208 can be precisely adjusted, thus making it applicable to label tapes of different widths and improving the applicability of the mechanism.

[0028] As can be seen from the above working process, the adjustment mechanism 203 set by the guide mechanism 2 can accurately adjust the position of the limit ring 208, thereby ensuring that the label tape is accurately positioned and horizontally transmitted when passing through the guide roller 207, reducing label offset and waste, and thus improving the labeling effect and work efficiency.

[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the limiting ring 208 is fixedly connected to the left side of the connecting plate 2038, and the limiting ring 208 is sleeved on the outside of the guide roller 207. The label detection head 209 is fixedly connected to the opposite side of the connecting plate 2038, and the label detection head 209 is electrically connected to the external detection system.

[0030] The label detection head 209, in conjunction with an external detection system, can detect the label position in real time. If a label is not positioned accurately on the label tape, it will promptly notify staff for handling, ensuring the accuracy of label delivery.

[0031] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the disassembly and assembly mechanism 206 consists of a guide bar 2061, a threaded rod 2065, a positioning post 2066, and a turntable 2067. The guide bar 2061 is symmetrically fixedly connected to the left and right sides of the connecting shaft 205. The guide roller 207 has symmetrically opened connecting grooves 2063 on its upper and lower sides. The connecting grooves 2063 have symmetrically opened grooves 2064 on its front and rear sides. The threaded rod 2065 is threadedly connected between the groove 2064 and the outer surface of the guide roller 207. The positioning post 2066 is rotatably connected to one side of the threaded rod 2065. The turntable 2067 is fixedly connected to the other side of the threaded rod 2065.

[0032] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the front and rear sides of the connecting shaft 205 are symmetrically provided with positioning grooves 2062, and the size of the positioning post 2066 is adapted to the positioning grooves 2062.

[0033] Rotating the turntable 2067 drives the threaded rod 2065 to rotate, thereby causing the positioning pin 2066 to insert into the positioning groove 2062, thus fixing the connection between the connecting shaft 205 and the guide roller 207, facilitating the disassembly or installation of the guide roller 207, and improving work efficiency.

[0034] This solution has the following working process: In use, the position of the two limiting rings 208 on the guide roller 207 is first adjusted via the adjusting mechanism 203 to ensure the label can pass smoothly through the guide roller 207. During adjustment, the handle 2037 is turned, driving the fixed shaft 2036 and the driven bevel gear 2035 to rotate, which in turn drives the active bevel gear 2034 and the lead screw 2032 to rotate. The rotation of the lead screw 2032 causes the cross block 2033 to slide within the cross groove 2031, moving the connecting plate 2038 and the limiting rings 208. Simultaneously, the pointer 2039 points to the scale line 210, allowing precise adjustment of the height of the limiting rings 208, ensuring the label tape passes accurately between the two limiting rings 208. Then, the label tape passes sequentially through the baffle 4, the sponge roller 5, and the fixed roller 6, finally winding around the outside of the take-up roller 7, completing the label application and take-up process.

[0035] Meanwhile, as the label tape passes through the guide roller 207, the label detection head 209 is fixed on the connecting plate 2038 and electrically connected to the external detection system. It can detect the position of the label on the label tape in real time to ensure that the label is accurately positioned on the label tape. If the label position is offset, a signal is sent to the external system to notify the staff to handle the situation.

[0036] When it is necessary to replace or maintain the guide roller 207, the operation is carried out through the disassembly and assembly mechanism 206. Rotating the turntable 2067 causes the threaded rod 2065 to drive the positioning pin 2066 out of the positioning groove 2062, thus releasing the connection shaft 205 from the guide roller 207. Then, the bolts are removed to detach the base plate 201 from the support plate 202, allowing the guide roller 207 to be removed. For installation, simply rotate the turntable 2067 in the opposite direction.

[0037] In summary: The adjusting mechanism 203 of the guiding mechanism 2 can precisely adjust the position of the limiting ring 208, thereby ensuring that the label tape is accurately positioned and horizontally transmitted when passing through the guide roller 207, reducing label offset and waste, and thus improving the labeling effect and work efficiency; the disassembly and assembly mechanism 206 can quickly disassemble and install the guide roller 207, which is simple in structure, convenient in operation, easy to maintain and replace, and improves the efficiency of the mechanism.
