Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of laminating equipment, more particularly to a straw recycling plywood production laminating equipment. BACKGROUND
[0002] Straw is the stem and leaf part left after the harvest of crops, mainly including the stems of crops such as wheat, rice, corn, cotton, and sugarcane. It is usually regarded as agricultural waste, but in recent years it has been actively explored as a renewable resource for energy, feed, and bio-based materials (such as paper pulp and artificial plywood). At present, when single boards are laminated, the single boards made of straw have smooth surfaces and are coated with glue, and under the action of pressure, the upper and lower single boards are easily misaligned, resulting in a large number of defective products, affecting production efficiency, and also causing waste of cost. To solve the above problems, a straw recycling plywood production laminating equipment is proposed in the present application. SUMMARY
[0003] The present application aims to provide a straw recycling plywood production laminating equipment that solves the problems of single board misalignment and uneven stress by positioning the single board and dynamically adjusting the height of the positioning mechanism.
[0004] To solve the above technical problems, the present application is realized by the following technical scheme: A straw recycling plywood production laminating equipment, comprising a machine body; The inside of the machine body is movably mounted with positioning stops, each group of positioning stops is located between adjacent hot pressing plates of the machine body, and each group of single positioning stops is distributed in the side area of the front, rear, left, and right directions. The positioning stop has a first working state and a second working state, the first working state of the positioning stop on the left and right sides is left and right sliding, and the first working state of the positioning stop on the front and rear sides is front and rear sliding. The second working state of the positioning stop, the height of the side edge perpendicular to the hot pressing plate decreases as the adjacent hot pressing plate approaches, and the side edge parallel to the hot pressing plate increases as the adjacent hot pressing plate approaches. A limiting frame is provided above the hot pressing plate and penetrates the positioning stops on the left and right sides, one side of the limiting frame is provided with a transition plate fixedly connected with the positioning stops on the front and rear sides, and the part of the limiting frame and the transition plate fixedly connected with the positioning stop is a fixed block.
[0005] The present application has the following advantages: 1. The slide and the telescopic device drive the adjacent positioning blocks to automatically move in the center. After a group of single boards are placed between adjacent hot pressing plates, they are automatically positioned at the center of the hot pressing plates, ensuring uniform force while avoiding local plate collapse and breakage caused by misplacement. 2. Through the bidirectional extension and retraction of the positioning block, the highest point of the positioning block can be automatically adjusted under the action of pressure when the adjacent hot pressing plates are close to each other, so that the side height is always consistent with the thickness of a group of single boards, effectively avoiding the problem of sliding dislocation of the single board after being pressed.

[0008] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0009] Please refer to Figure 1 As shown in Fig. 4, the present application provides a straw recycling plywood production laminating equipment.
[0010] As Figure 1 As shown in Fig. 4, the present application provides a straw recycling plywood production laminating equipment, which comprises a machine body 1, A positioning block 4 is movably installed in the inside of the machine body 1, which is a high-temperature-resistant belt body with an end face in the shape of a right-angled triangle. A plurality of positioning blocks 4 are a group, located between adjacent hot pressing plates of the machine body 1. A single positioning block 4 in each group is distributed in the side edge area of the front, rear, left and right directions. The positioning blocks 4 in the left and right side areas are located in the front and rear center, used for positioning the left and right side edges of the veneer. The positioning blocks 4 in the front and rear side areas are symmetrically distributed with the left and right centers as boundaries, used for positioning the front and rear side edges of the veneer. The positioning blocks 4 in the left and right side areas horizontally slide along the left and right directions, and the positioning blocks 4 in the front and rear side areas horizontally slide along the front and rear directions. When the baffle is placed inside the hot pressing plate, the four side positioning blocks 4 are simultaneously centered and moved, thereby driving the veneer to move to the center position of the hot pressing plate, ensuring that the forces on each area of the veneer are uniform, and avoiding the conditions of partial collapse and fragmentation. Further, the side edge of the positioning block 4 perpendicular to the hot pressing plate is pushed downward when the hot pressing plate is pressed down. The height of the side edge is lowered to keep consistent with the thickness of each group of veneers. The horizontal side edge below the positioning block 4 is elongated with the lowering of the height of the vertical side edge, and the elongated direction is away from the horizontal side edge. Further, a limiting frame 5 is arranged above each layer of hot pressing plate, extending outward from the front and rear of the hot pressing plate. The middle part of the limiting frame 5 is fixedly connected with the positioning blocks 4 in the left and right side areas. The plate body part of the limiting frame 5 outwardly extending from one end of the positioning block 4 in the front and rear area is a transfer plate 54. The overlapping part of the limiting frame 5 and the transfer plate 54 fixedly connected with the positioning block 4 is a fixed block 51 thickened upward. As Figure 1 The outer sides of the front and rear of the machine body 1 are provided with slide seats 2 capable of sliding left and right, distributed in the end areas of the front and rear of the hot pressing plate. The lower end of the slide seat 2 protrudes outward as a protruding block 21. Two through holes are formed in the inside of the protruding block 21, one in front of the other. One of the two through holes is a threaded hole, and the other is a smooth hole. The inside of the slide seat 2 is provided with a groove in the upward and downward directions. The two ends of the groove are provided with positioning rods 22. The two box walls of the fuselage 1 are fixedly installed with fixed frames 3 on the front and back sides, and a bidirectional transmission rod 31 and a guide rod 32 are rotatably installed between the adjacent fixed frames 3 on the left and right sides, the bidirectional transmission rod is a rod body mechanism composed of two sections of ball screws with different rotation directions, the two sections of ball screws are in transmission connection with the screw holes in the protrusion 21, and the bidirectional transmission rod is driven to rotate by the rotary motor outside the fixed frame 3, and the guide rod 32 is in sliding connection with the protrusion 21.
[0011] As Figure 2 The front and back ends of the limiting frame 5 extend with support plates 52 in a T shape and are in up-down sliding connection with the groove bodies on the inner side of the sliding seat 2, and the two ends of the support plates 52 are provided with hole bodies and are in sliding connection with the positioning rods 22. The side of the limiting frame 5 extends perpendicularly towards one side of the single board, and a sub plate 53 is vertically extended on the side, one end of the sub plate 53 is fixedly provided with a clamping sleeve 531, the clamping sleeve 531 is sleeved outside the plate body in the front and back directions of the adapter plate 54, so that the adapter plate 54 moves up and down synchronously with the limiting frame 5. Further, the clamping sleeve 531 extends upwards away from one side of the single board and has a protruding plate 5311, the plate body of the adapter plate 54 extends upwards away from one end of the single board and has a side plate 541, and the two plate bodies are fixedly connected with an extender 55 for driving the front and back positioning stops 4 to move close to the single board, so as to form a front and back pushing force to achieve the effect of centering positioning.
[0012] As Figure 4 The vertical side and the inclined side of the positioning stop 4 are provided with a top shaft one 56a at an included angle, the lower end of the top shaft one 56a is rotatably installed with a top plate one 561a, and the horizontal side and the inclined side of the positioning stop 4 are provided with a top shaft two 56b at an included angle, the top shaft two 56b is rotatably installed with a top plate two 561b adjacent to one side of the fixed block 51. The inside of the fixed block 51 is provided with a 1 hole 511 and a slide 512 that are staggered towards the top plate two 561b, the slide 512 is a reverse T-shaped structure, the upper side of the fixed block 51 is provided with a sliding frame 57, and the two ends extend downwards with a reverse T-shaped block that is in sliding connection with the slide 512. Further, the upper end of the sliding frame 57 is rotatably installed with a rotary seat 571, the upper side of the rotary seat 571 is a plane structure, the upper end of the rotary seat 571 and the inside of the hole 511 are both installed with a spring telescopic rod 58 that is connected to the top plate one 561a and the top plate two 561b respectively.
[0013] In use, the left and right adjacent slide blocks 2 are simultaneously moved to the center by rotating the motor, and the positioning stop 4 is driven by the limiting frame 5 to push the single board, forming the centering positioning in the left-right direction. Then the contraction of the extender 55 drives the front and rear slide blocks 2 to simultaneously move to the center, forming the centering positioning of the single board in the front-rear direction. Further, the downward pressing of the hot pressing plate first presses against the top of the vertical side of the positioning stop 4, driving the top shaft one 56a to press downward. At this time, the slide block 57 slides to the side of the top shaft two 56b, and the vertical side hole 511 releases the pushing force, pushing the top shaft two 56b away, thereby straightening the vertical side, so that the vertical side remains in a flat state, thereby forming resistance to the single board, preventing the single board from being misaligned under the action of pressure. When the hot pressing plate is separated upward, the hole 511 releases the pushing force to drive the top shaft one 56a to move upward, thereby restoring the positioning stop 4 to its original state.
