Abstract

The utility model relates to the technical field of label feeding equipment, in particular to a label feeding device. The bar code label feeding device can achieve automatic feeding of bar code labels, avoids damage when the labels are manually stripped, is small in size, convenient and fast, and saves labor cost of assembly manufacturers. Through the arrangement of the winding mechanism, the power source can drive the power roller to rotate and drive the winding roller to rotate at the same time, and when more and more waste rolls are accumulated, the angular velocity difference between the winding roller and the power roller is larger and larger; therefore, the condition that the same linear speed but different angles are needed between the winding roller and the power roller can be eliminated through slipping and idling of the round belt between the winding roller and the power roller.

Description

Technical Field

[0001] This application relates to the technical field of label feeding equipment, specifically label feeding devices. Background Technology

[0002] Due to the continuous development of photovoltaic (PV) modules, PV module manufacturers need to affix barcode labels containing PV module identification information to the modules for easier viewing and data collection. Currently, these barcode labels are manually peeled off and re-attached, which can easily damage the labels and increase labor costs for PV module manufacturers. Furthermore, traditional label feeding machines are too bulky and unsuitable for module manufacturing production lines. Utility Model Content

[0003] The purpose of this invention is to provide a label feeding device that can automatically feed labels, avoid damage when manually peeling labels, and is small in size, convenient and quick, saving labor costs for component manufacturers.

[0004] The technical solution of this utility model is as follows:

[0005] The label feeding device includes a peeling mechanism, a winding mechanism, and an unwinding mechanism. The winding mechanism includes a pressure roller assembly, a winding roller, and a power source. The pressure roller assembly includes a pressure roller and a power roller. The pressure roller and the power roller are closely attached to each other. The power roller and the winding roller are driven by a round belt. The power source drives the power roller to rotate.

[0006] By setting up a winding mechanism, the power source can drive the drive drum to rotate while simultaneously driving the winding drum to rotate. As more and more waste rolls accumulate, the angular velocity difference between the winding drum and the drive drum becomes larger and larger. This can be achieved by the slippage of the circular belt between the winding drum and the drive drum, which eliminates the situation where the two need to have the same linear velocity but different angles.

[0007] The winding mechanism includes a guide plate located below the pressure roller assembly, with the guide plate guiding in the direction of the winding drum.

[0008] The compression roller includes a separation structure, which includes an eccentric wheel and a handle. The eccentric wheel is installed on both sides of the compression roller, and the handle is connected to the eccentric wheel.

[0009] The guide plate and separation structure make it easy to manually thread the material.

[0010] The stripping mechanism includes a stripping plate and a receiving platform. The receiving platform is close to the stripping plate with a gap, and the top surface of the receiving platform is at the same horizontal level as the top surface of the stripping plate.

[0011] By setting up a peeling mechanism, the labels on the label roll can be continuously peeled off in conjunction with the operation of the winding mechanism.

[0012] The peeling plate includes an integrally formed plate body, which includes a fixed end and a peeling end. One side of the peeling end is kept horizontal and is on the same plane as the receiving platform. The other side of the peeling end is angled downward at 20°-45° and maintains an acute angle with one side of the peeling end.

[0013] The stripping mechanism also includes a label sensing component, which is located near the receiving platform.

[0014] By setting up the label sensing component, it is possible to sense whether the label is in place on the peeling platform.

[0015] The tag sensing component includes a position adjustment structure, which includes a guide post, a fixed base, and a spring. The guide post passes through the fixed base, the spring is sleeved on the guide post and abuts against the fixed base, and the fixed base is also equipped with an adjustment screw.

[0016] By adjusting the position of the sensor, the sensor position can be manually adjusted according to the actual label size.

[0017] The label feeding device includes a label straightening component, and at least one label straightening component is provided. The label straightening component is installed on the label feeding path of the label feeding device.

[0018] By setting up a label straightening component on the label feeding path, the label roll can be continuously straightened during feeding, ensuring that the peeled labels fall accurately into the sensing range of the label sensing component. This also ensures the accuracy of the label feeding position and improves the success rate of label acquisition at subsequent workstations.

[0019] In summary, the winding mechanism allows the power source to drive both the drive roller and the winding roller simultaneously. As the waste rolls accumulate, the angular velocity difference between the winding roller and the drive roller increases. This difference is mitigated by the slippage of the belt between the two rollers, eliminating the need for identical linear velocities but different angles. The guide plate and separation structure facilitate manual material feeding. The peeling mechanism works in conjunction with the winding mechanism to continuously peel labels from the label rolls. The label sensing component detects whether the labels are in place on the receiving platform. The position adjustment structure allows for manual adjustment of the sensing position based on the actual label size. The label straightening component along the label feeding path continuously straightens the label rolls during feeding, ensuring that peeled labels accurately fall within the sensing range of the label sensing component. This guarantees accurate label feeding position and improves the success rate of label retrieval at subsequent stations. Attached Figure Description

[0029] The purpose of this invention is to provide a label feeding device that can automatically feed barcode labels, avoid damage when manually peeling off labels, and is small in size, convenient and fast, saving labor costs for component manufacturers.

[0030] according to Figure 1 As shown, the label feeding device includes a winding mechanism, a peeling mechanism, and an unwinding mechanism, with the unwinding mechanism located above the winding mechanism.

[0031] according to Figure 2 and Figure 3As shown, in this embodiment, the winding mechanism includes a pressure roller assembly, a winding drum 103, and a power source. In actual use, the power source is a motor 104. The pressure roller assembly includes a pressure drum 101 and a power drum 102. The pressure drum 101, the power drum 102, and the winding drum 103 are all fitted with rotating shafts. The pressure drum 101 and the power drum 102 are close to each other and pressed tightly. A round pulley 105 is fixedly installed at one end of the power drum 102 and the winding drum 103, which is driven by a round belt 106. The motor 104 is located between the power drum 102 and the winding drum 103. A synchronous belt drive pulley 107 is installed on the rotating shaft of the motor 104. A synchronous belt driven pulley 108 is also installed on the power drum 102. The motor 104 drives the power drum 102 to rotate through the synchronous belt 109, which in turn drives the winding drum 103 to rotate. By configuring the winding mechanism, the motor 104 can drive the drive roller 102 to rotate while simultaneously driving the winding roller 103 to rotate. As more and more waste rolls accumulate, the angular velocity difference between the winding roller 103 and the drive roller 102 increases. This can be mitigated by the slippage of the circular belt 106 between the winding roller 103 and the drive roller 102, eliminating the need for them to have the same linear velocity but different angles. A guide plate 110 is also provided below the pressure roller assembly, with the guide plate 110 pointing towards the winding roller 103. The pressure roller 101 is also provided with a separation structure, which includes an eccentric wheel 111 and a handle 112. The eccentric wheel 111 is installed on both sides of the pressure roller 101, and the handle 112 is sleeved on the rotating shaft of the pressure roller 101 and connected to the eccentric wheel 111. With the setting of the guide plate 110 and the separation structure, the pressure roller 101 and the power roller 102 can be separated by rotating the handle 112, so that the gap between them is increased, which makes it easier for manual feeding of the label roll through the pressure roller assembly. The guide plate 110 provided below the pressure roller assembly allows the passing roll to be fed in a predetermined feeding direction, which facilitates manual feeding and material changing.

[0032] according to Figures 4 to 6As shown, in this embodiment, the peeling mechanism includes a peeling plate 201 and a receiving platform 202. The receiving platform 202 is close to the peeling plate 201 and has a gap. The top surface of the receiving platform 202 is at the same horizontal level as the top surface of the peeling plate 201. With the peeling mechanism in place, it can continuously peel labels off the label roll in conjunction with the operation of the winding mechanism. The peeling plate 201 includes an integrally formed plate body, comprising a fixed end and a peeling end. One side of the peeling end is horizontal and on the same plane as the receiving platform 202, while the other side of the peeling end is angled downwards at 30° and maintains an acute angle with one side of the peeling end. The peeling mechanism also includes a label sensing component, located near the receiving platform 202. The label sensing component includes a position adjustment structure, comprising a guide post 203, a fixed seat 204, and a spring 205. The guide post 203 passes through the fixed seat 204, and the spring 205 is sleeved on the guide post 203 and abuts against the fixed seat 204. The fixed seat 204 is also equipped with an adjusting screw 206. The label sensing component can detect whether the label is in place on the receiving platform 202. The position adjustment structure of the label sensing component allows for manual adjustment of the sensing position according to the actual label size.

[0033] according to Figure 7 As shown, an unwinding mechanism is provided above the winding mechanism. The unwinding mechanism includes a cantilever bracket 301 and an unwinding roller 302. A rotating shaft is installed on the cantilever bracket 301, and the unwinding roller 302 is sleeved on the rotating shaft.

[0034] according to Figure 8 As shown, the label feeding device also includes label straightening components. Two label straightening components are provided, one on the winding mechanism and the other on the peeling mechanism, both positioned along the label feeding path. Each label straightening component includes straightening guide rods 401, straightening blocks 402, and fixing screws 403. The two straightening blocks 402 are fitted onto the two straightening guide rods 401 through through-holes. The fixing screws 403 penetrate the straightening blocks 402 and abut against the straightening guide rods 401. Tightening the fixing screws 403 adjusts the position of the two straightening blocks 402 on the straightening guide rods 401, thus adapting to the spacing width of the label roll. By setting the label straightening components along the label feeding path, the label roll can be continuously straightened during feeding, ensuring that the peeled labels accurately fall within the sensing range of the label sensing component. This also ensures the accuracy of the label feeding position and improves the success rate of label acquisition at subsequent workstations.
