Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, in particular to an automatic feeding device for leather hot melt adhesive. Background Art

[0002] In existing leather processing production lines, hot melt adhesive feeding is mostly done manually or semi-automatically, which has problems such as high labor intensity, low efficiency, and poor precision. With the continuous advancement of hot melt adhesive technology and the popularization of automated equipment, the development of an efficient and accurate leather hot melt adhesive automated feeding device has become an urgent need in the industry.

[0003] For example, a Chinese patent discloses "hot-melt adhesive dot-bonded leather" (patent number: CN201320390817.5), which includes leather material, on which hot-melt adhesive nets or hot-melt adhesive dots are bonded, and the leather material can be bonded with other fabrics or materials at low temperature through the hot-melt adhesive nets or hot-melt adhesive dots, and the hot-melt adhesive nets or hot-melt adhesive dots on the release paper can be transferred to the leather material at any time, and the hot-melt adhesive nets or hot-melt adhesive dots on the leather material can be attached to other materials at any time, without being restricted by the shape and variety of the materials, saving labor, time and space. Since the leather material is bonded with dot-shaped or mesh-shaped hot-melt adhesive (such as PA, EVA), it is breathable after bonding, can maintain the feel of the material, is resistant to aging, has good shape retention, and is a pollution-free hot-melt adhesive.

[0004] However, the above-mentioned patent document does not point out that the bonding method of hot melt adhesive may have certain limitations on the shape and size of leather and other materials, especially in the bonding of complex shapes or large-sized materials. This may cause difficulties, which will lead to a decrease in the efficiency of hot melt adhesive feeding on leather. If the surface of the leather is uneven, the effect of hot melt adhesive feeding will also be greatly reduced. Summary of the invention

[0051] It should be further explained that the detection head 130 is a sensor that can sense the contact reaction head 127 at the top of the lifting plate 126 and perform signal transmission to achieve automatic control.

[0052] It is worth further explaining that a material interface for communicating with the hot melt adhesive raw material is provided at the top of the hot melt adhesive feeder 108 .

[0053] Furthermore, a support rope 128 can be wound between the lifting plates 126, and the support rope 128 can be used to support the leather fabric.

[0054] When using this solution, first drive the whole to move to the working position, and play a role of stable support through the support base 101. At this time, the leather to be loaded is placed on the top of the working platform 105, and the lifting motor 133 in the telescopic guide cylinder 116 is started. When the lifting motor 133 is started, it can drive the lifting thread shaft 134 to rotate, and then drive the lifting plate 126 to move upward through the rotation of the lifting thread shaft 134 and move upward through the contact reaction head 127 and abut against the bottom surface of the leather, thereby playing a role of stable support. When the contact reaction head 127 does not contact the bottom of the leather, the lifting motor 133 rotates to drive the lifting plate 126 to reset.

[0055] When hot melt adhesive is automatically fed, first connect the top of the hot melt adhesive feeder 108 to the hot melt adhesive raw material pipeline. At this time, the moving components 1001 on both sides are started, and the moving cylinder 113 controls and drives the moving slider 104 to move forward and backward along the moving slide rail rod 112. At this time, the moving sliders 104 on both sides move to drive the cross support plate 111 of the cross frame to move, and drive the hot melt adhesive feeder 108 to move. At this time, the hot melt adhesive feeder 108 outputs the connected hot melt adhesive raw material to the leather surface through the feeding nozzle 132. At the same time, when the translation cylinder 106 is started, it can control the translation support plate 107 to move along the translation rail rod 109. At this time, as the translation support plate 107 moves and drives the hot melt adhesive feeder 108 to move horizontally, the automatic output of the hot melt adhesive raw material is realized, thereby realizing the automatic feeding effect of leather.

[0056] During the automatic feeding of hot melt adhesive, the detection head 130 is used for sensing, and the contact reaction head 127 in contact with the bottom surface of the leather is used for sensing, and the specific position of the hot melt adhesive feeder 108 after moving above the leather can be determined, and the regional accuracy of the hot melt adhesive feeding of the leather can be improved by determining the specific position in real time, thereby further improving the efficiency of the automatic feeding of the leather hot melt adhesive.

[0057] When the leather surface is wrinkled, such as Figure 8 As shown, at this time, the cylinder in the side wall of the adjusting slide groove 119 is started, and the cylinder can drive the adjusting slide plate 118 to adjust the guiding displacement of the slide rod 120, and move from one side of the upper surface of the leather to the other side through the lateral push strip 122 of the horizontal frame, and the lower surface of the lateral push strip 122 is against the leather surface, and the wrinkles on the leather surface are flattened. If the leather is more deformed, at this time, the rotating mechanism provided in the rotator 135 is started, and the rotating mechanism can drive the rotating strip 121 to rotate and flip, and rotate to a certain angle through the rotating strips 121 on both sides, thereby facilitating the removal of wrinkles on the deformed leather fabric surface.

[0058] When the leather to be loaded is small, such as Figure 5-Figure 7As shown, at this time, the lifting plate 126 at a specific position is controlled to move upward to the upper side of the upper end surface of the working platform 105, and the support rope 128 is wrapped around the surface of the moving and extended lifting plate 126, and the support rope 128 is fixed to the two contact reaction heads 127 at the top to form a support wire net for supporting small leathers. At this time, when hot melt adhesive is fed to small leathers, the position positioning is confirmed by the extended side lifting plates 126, thereby improving the accuracy of hot melt adhesive feeding for small leathers, thereby improving the efficiency of automatic hot melt adhesive feeding for leathers, and being able to adapt to leathers of different sizes and shapes.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
