Description

Technical Field

[0001] The utility model relates to the field of door panel hot pressing gluing machines, in particular to a gluing device. Background Art

[0002] A hot press gluing machine is a special equipment that can perform hot pressing on composite fabrics and anti-theft door panels to quickly achieve gluing of composite fabrics or anti-theft doors. The traditional hot press gluing machine mainly consists of a machine body, a number of pressing plates mounted on the machine body and stacked, and a driving mechanism that drives the pressing plates to press or separate. There is a pressing space between each pressing plate, and the machine body is provided with a heat energy generator that can add heat energy to the inside of the pressing plate. During use, the object to be glued needs to be placed in the pressing space, and then the pressing plate is driven by the driving mechanism to thermally glue the object. However, at present, the placement of the object to be glued and the output from the machine body are performed manually, which is not only cumbersome and requires more manpower, but also poses a greater safety hazard. It also prolongs the processing time and has a low gluing efficiency.

[0003] The applicant has proposed an intelligent single-piece flow hot pressing gluing machine with publication number CN113172983A, which adopts a gluing device, which includes a body, a plurality of pressing plates mounted on the body and stacked, and a driving mechanism for driving the pressing plates to press or separate, and a pressing space is provided between each pressing plate. A heat energy generator that can add heat energy to the inside of the pressing plate is provided on the body, and input devices for objects to be glued and output devices for completed glued objects are provided on both sides of the body. The input device for objects to be glued includes a frame and an input platform mounted on the frame, and the output device for completed glued objects includes a frame and The output platform mounted on the frame body is characterized in that: a conveyor belt is provided at one end of the input platform close to the gluing device, a transfer bracket mechanism is mounted on the input platform, and the transfer bracket mechanism includes relatively set brackets, a bracket claw which is set at one end of the bracket and can be opened and closed, a bracket driving mechanism which drives the bracket claw to slide back and forth along the horizontal position of the bracket, and a bracket claw opening and closing structure which causes the bracket claw to open and be in a parallel position with the bracket or causes the bracket claw to close and be in a vertical position with the bracket, and a door suction device which adsorbs the anti-theft door to be glued when the bracket driving mechanism drives the bracket to move is provided on the opposite side of the two brackets;

[0004] The current fully automatic hot-press gluing machine is to place the anti-theft door to be glued on the input platform, lift the anti-theft door to be glued by the lifting mechanism to adapt to the pressing space of different heights, and then transport it into the pressing space, that is, to lift the entire conveying platform, but this method not only has the problems of slow speed and complex structure, but also the biggest problem is that, in the process of entering the pressing space, part of the anti-theft door to be glued is located on the conveying platform, and part of it is located in the pressing space. The conveying speeds of the two ends of the anti-theft door to be glued on the conveying platform and in the pressing space are not consistent, resulting in damage to the paint or packaging film on the surface of the anti-theft door. In severe cases, long strip marks will appear on the anti-theft door after gluing (due to the curled packaging film). The film is left on the surface of the anti-theft door by the pressure of the pressing plate during gluing), which causes the anti-theft door to become a defective product after gluing. The present invention arranges a driving mechanism on the body of the gluing device. The driving mechanism can directly select the driving mechanism for driving the lifting of the pressing plate in the prior art, such as the driving mechanism disclosed in Patent No. CN106113169B, and drives the pressing plate to be positioned by the driving mechanism, so as to select the pressing space. Since the present invention transports by arranging a conveyor belt and a transfer bracket mechanism, when the anti-theft door to be glued is completely located on the conveyor belt and one end is on the bracket claw, the conveyor belt starts to transport. During transportation, the bracket driving mechanism of the transfer bracket mechanism keeps synchronized with the conveyor belt speed, so that the anti-theft door to be glued enters the pressing space. During the process, the speed of the driven side is kept synchronous, thereby completely avoiding the problem of damaging the paint or packaging film on the surface of the anti-theft door to be glued during transportation. The surface of the anti-theft door after gluing is intact, which greatly improves the yield rate. The transfer bracket mechanism of the present invention has another function. When the anti-theft door to be glued in a certain pressing space in the gluing device is completed, the transfer bracket mechanism is used to push the glued anti-theft door out of the pressing space and then onto the output platform. The mechanism realizes two functions, which greatly simplifies the equipment complexity of the existing hot pressing gluing machine. In actual production, it is found that the mechanism still has defects, that is, the anti-theft door to be glued may retreat when being transported on the bracket claw and the conveyor belt. The occurrence of this phenomenon It will also damage the paint and film on the surface of the anti-theft door to be glued. In order to solve this problem, the other side of the anti-theft door to be glued is adsorbed by the door suction device while the transfer bracket mechanism is conveying. Since the door suction device and the transfer bracket mechanism move synchronously, the phenomenon of the anti-theft door to be glued retreating is well solved, and the yield rate is greatly improved. After the anti-theft door to be glued is completely pressed into the space, the bracket claw opens the door suction device under the action of the bracket claw opening and closing structure to release the adsorption of the anti-theft door to be glued, and returns to its original position with the bracket. Since the technical solution provided by the present invention only conveys one anti-theft door to be glued into the pressing space at a time, and conveys the anti-theft door to be glued into the pressing space again after the pressing output is completed, it is called a single-piece flow hot pressing gluing machine;

[0005] However, this type of gluing machine has the problems of complex equipment and low efficiency. The efficiency of the suction and conveying of the door suction device is not as good as the efficiency of the traditional conveyor belt method. Due to the development of materials science, the current belt material can fully achieve transportation without damaging the paint on the surface of the door panel; therefore, the applicant has developed a gluing device based on belt conveyor. Summary of the invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0007] A gluing device is provided.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gluing device, comprising a body, a plurality of pressing plates arranged on the body and stacked, and a driving mechanism for driving the pressing plates to press or separate, a pressing space being provided between each pressing plate, a load box being provided at one end of the body away from the ground, a heat energy generator being provided on the body for adding heat energy to the inside of the pressing plates, characterized in that: the driving mechanism comprises a driving source, a driving rod being provided at one end of the driving source and being capable of being raised and lowered under the drive of the driving source, a lifting frame being connected to the driving rod, a conveyor belt structure being provided around each pressing plate and capable of causing a glued object located on the pressing plate to move from an external input platform to an external output platform, a positioning structure being provided on the lifting frame for selecting the pressing space and a second positioning structure for synchronously lifting the pressing plate located below the selected pressing space.

[0009] By adopting the above technical scheme, thanks to the progress of materials science, the conveyor belt in the prior art can already realize the conveying of painted or coated door panels without speed difference without damaging the paint surface and the film surface. For this reason, the applicant adopts the conveying method of this type of belt conveyor structure as the conveying method of the gluing machine assembly line. The belt conveying method has the advantages of fast conveying speed and simpler structure than the single-piece hot press gluing machine in CN113172983A. There is no need to set up a transfer bracket structure for single-piece conveying. The working principle of this technical scheme is to convey the materials to be glued (door panels) into each gluing space of the gluing device in turn through an external input device for objects to be glued. The materials to be glued in the gluing space are heated by the pressing plate and under the pressure of the load box above. After gluing is completed, the glued material is then transported to an external device for outputting the glued object. The present invention outputs the material through a conveyor belt structure wound on the pressing plate. There is a gap between the conveyor belt structure wound on the lowest pressing plate and the bottom of the gluing device for the conveyor belt to drive. Taking the material on the lowest pressing plate that needs to be output as an example, during output, since the material is in contact with the upper pressing plate on the top and is pressed by a load box on the top, the positioning structure selects the gluing space of this layer and lifts up all the pressing plates above the gluing space so that the pressing plates are not in contact with the top. The conveyor belt structure wound on this layer of pressing plates can drive and output the material, and the external device for outputting the glued object on the other side of the gluing device The output platform in the middle reaches the corresponding position of the layer of plywood under the action of the output lifting device, and receives the finished gluing material output by the conveyor belt structure for storage or backward transmission for edge pressing or other processes. Taking the material on the plywood layer above the lowest layer of plywood as an example, when the finished gluing material on the layer of plywood needs to be output, the positioning mechanism lifts all the plywood and the load box above the plywood where the material is located, so that the finished gluing material on the layer of plywood does not contact with other objects above. Since there is material under the layer of plywood, the lower layer of plywood needs to be slightly lifted. The layer of plywood is slightly lifted under the action of the second positioning structure so that the plywood set on the layer of plywood can be The conveyor belt structure can transmit the finished gluing material to the output platform in the finished gluing object output device. Under the action of the output lifting device, the output platform arrives at the corresponding position of the layer of plywood to receive the finished gluing material for storage or transmits it backward for edge pressing or other processes. The present invention arranges a conveyor belt structure on each plywood and cooperates with a second positioning structure to achieve a method in which the conveyor belt structure on the plywood inputs the material to be glued obliquely and outputs the finished gluing material. In the prior art such as CN106113169B, the input of the material to be glued and the output of the finished gluing object are matched by lifting the gluing device. The gluing device is heavy and the lifting speed is slow. The method of the present invention significantly improves the production efficiency.

[0010] The above-mentioned gluing device can be further configured as follows: the conveyor belt structure includes a conveyor belt wound around the circumference of the pressing plate, and the two sides of the conveyor belt in the width direction are smaller than the width of the pressing plate to form a positioning area in contact with the second positioning structure, and opposite mounting seats are installed at both ends of the pressing plate, and a rotatable tensioning shaft is passed through the two opposite mounting seats, and one of the tensioning shafts is provided with a belt driving source for driving the tensioning shaft to rotate and thereby drive the conveyor belt to convey, and a tensioning adjustment structure is provided between one side mounting seat and the tensioning shaft.

[0011] By adopting the above technical solution, the belt driving source is set as a servo motor with higher precision. Since it is necessary to ensure that the conveyor belt can be driven by the belt driving source when the pressing plate is lifted by the second positioning mechanism, the conveyor belt cannot be set as wide as the pressing plate, but a distance needs to be left to form a positioning area in contact with the second positioning structure, thereby ensuring that the conveyor belt can be driven normally when the second positioning structure lifts the pressing plate. Since the gluing device of the gluing machine is large in size, the components on it are often transported to the site for assembly during transportation. Therefore, the tensioning adjustment structure set up can enable the assemblers to adjust the belt tension on site according to needs, thereby improving assembly efficiency and versatility.

[0012] The above-mentioned gluing device can be further configured as follows: the tensioning adjustment structure includes an adjustment slot arranged on a mounting seat at the other end of the mounting seat opposite to one end of the belt driving source, and the tensioning shaft can change its distance from the pressing plate in the adjustment slot.

[0013] By adopting the above technical solution, an adjustment slot is opened on the mounting seat on one side (generally opposite to the belt drive source), so that the tensioning shaft at this location can adjust the distance between itself and the pressing plate in the adjustment slot, thereby adjusting the tension of the conveyor belt to better adapt to on-site assembly.

[0014] The above-mentioned gluing device can be further configured as follows: the positioning structure includes at least one group of retractable plug-in board components arranged relatively on both sides of the lifting frame, one end of the plug-in board component can extend into the pressing space of the gluing device, and the plug-in board component is fixedly connected to the lifting frame through a plug-in board mounting seat.

[0015] By adopting the above technical solution, the plug plate assembly is fixedly installed on the lifting frame through the plug plate mounting seat. When the gluing device needs to select a certain pressing space, the plug plate assembly is inserted into the corresponding pressing space. Under the action of the driving source, the lifting frame is lifted up to lift all the components above the pressing space, thereby opening the corresponding pressing space for subsequent processes.

[0016] The above-mentioned gluing device can be further configured as follows: the plug plate assembly includes a plug plate, one end of the plug plate is connected to a plug plate driving cylinder for driving the plug plate to extend and retract, the plug plate driving cylinder is connected to the plug plate mounting seat and the piston rod of the plug plate driving cylinder passes through the plug plate mounting seat and is fixedly connected to the plug plate, and a plug plate guide structure is provided between the outer periphery of the plug plate and the plug plate mounting seat.

[0017] By adopting the above technical solution, the plug plate assembly is driven by the plug plate driving cylinder, the response speed is fast and the structure is stable. The provided plug plate guide structure can guide the movement trajectory of the plug plate when it is extended, improve the straightness of the plug plate after it is extended, and avoid the problem of poor contact between the plug plate and the pressing plate resulting in a short service life of the plug plate.

[0018] The above-mentioned gluing device can be further configured as follows: the plug-in plate guide structure includes a guide sleeve at one end fixedly connected to the plug-in plate mounting seat, one end of the guide sleeve passes through the lifting frame and extends toward the plug-in plate and surrounds the plug-in plate to form a plug-in plate guide cavity, and the plug-in plate can be extended out of the plug-in plate guide cavity under the action of the plug-in plate driving cylinder.

[0019] By adopting the above technical solution, one side of the guide sleeve is first connected to the plug-in plate mounting seat, and the other side is fixedly installed on the lifting frame to improve the integration. By covering the plug-in plate in the guide cavity of the guide sleeve, on the one hand, it can protect the plug-in plate. On the other hand, the shape of the guide cavity is adapted to the plug-in plate, which plays a role in guiding the extension direction of the plug-in plate.

[0020] The above-mentioned gluing device can be further configured as follows: the second positioning structure includes a hanging seat, a notch that matches the thickness of the lifting frame is opened on one side of the hanging seat, and the lifting frame is provided with a hanging mounting platform for installing the hanging seat, the hanging seat is installed on the hanging mounting platform through fasteners and is clamped on the lifting frame through the notch, a hanging slot is provided in the hanging seat, and the hanging seat is connected to a hanging cylinder at one end of the hanging slot, and a hanging plate that matches the shape of the hanging slot is connected to the cylinder rod of the hanging cylinder, and the hanging plate can pass through the hanging slot under the action of the hanging cylinder.

[0021] By adopting the above technical solution, the second positioning structure and the positioning structure are staggered, and the specific distance control is that when the plug-in plate assembly extends into the pressing space, the hanging table plate of the second positioning structure can lift the lower pressing plate under the pressing plate under the pressing space, and one end of the hanging table seat is installed on the hanging table mounting platform through fasteners and is also connected to the lifting frame through the notch, which is firmly fixed. At the same time, the hanging table seat also plays a role in protecting the hanging table plate. The hanging table slot is set to adapt to the shape of the hanging table plate and plays a guiding role for the hanging table plate.

[0022] The above-mentioned gluing device may be further configured as follows: a plurality of sets of relatively arranged lifting guide structures are arranged on the periphery of the lifting frame.

[0023] When adopting the above technical solution, since the lifting frame needs to bear the weight of multiple components such as adhesives and pressed plates during the lifting process, it is necessary to ensure its stability during the lifting process. Otherwise, uneven force may easily occur on both sides of the lifting frame, resulting in unstable operation. The utility model ensures the smooth lifting of the lifting frame by arranging multiple groups of relatively arranged lifting guide structures on the circumference of the lifting frame, improves the stability of the device, and thus increases the service life of the device.

[0024] The above-mentioned gluing device can be further configured as follows: the lifting guide structure includes an outer guide seat of the lifting frame installed on one side of the lifting frame and an inner guide seat of the lifting frame installed on the other side of the lifting frame and arranged opposite to the outer guide seat of the lifting frame, one end of the outer guide seat of the lifting frame and the inner guide seat of the lifting frame are both provided with rotatable guide wheels, and the outer guide seat of the lifting frame and the inner guide seat of the lifting frame are connected by a rotatable connecting shaft.

[0025] By adopting the above technical scheme, the inner and outer sides of the lifting frame are guided respectively by the guide wheels arranged on the relatively arranged outer guide seat of the lifting frame and the inner guide seat of the lifting frame, and the synchronization degree is high. The inner guide seat of the lifting frame and the outer guide seat of the lifting frame are connected by a rotatable connecting shaft, thereby ensuring the synchronization between the inner guide seat of the lifting frame and the outer guide seat of the lifting frame. In order to further improve the synchronization degree, a lifting synchronization gear can be installed at a position where the connecting shaft is located between the inner guide seat of the lifting frame and the outer guide seat of the lifting frame, and a lifting synchronization rack meshing with the lifting synchronization gear is provided on the body of the gluing device to further improve stability.

[0026] The above-mentioned gluing device may be further configured as follows: the driving source is an oil cylinder.

[0027] By adopting the above technical solution, the versatility of the driving source is improved by setting the driving source as a cylinder. Of course, the driving source can also be set as a driving motor or a driving cylinder, but considering factors such as the weight of the parts of the gluing device and the lifting speed, setting it as a driving cylinder is the most preferred solution.

[0028] The beneficial effects of the utility model are as follows: belts are arranged on each layer of the plywood for conveying, and the conveying efficiency is high. The positioning structure and the second positioning structure arranged on the lifting frame can synchronously lift the pressing space to be selected and the pressing plate under the pressing space, and cooperate with the conveyor belt structure arranged on each pressing plate to achieve active output of the gluing material on each layer. The driving source is arranged on the ground on both sides of the machine body, which reduces the design requirements of the machine body and improves the installation and maintenance efficiency.

[0042] Thanks to the progress in materials science, the conveyor belts in the prior art can already convey the painted or film-coated door panels without speed difference without damaging the paint surface and the film surface. For this reason, the applicant adopts this type of belt conveyor structure as the conveying method of the gluing machine assembly line. The belt conveyor method has a fast conveying speed and a simpler structure than the single-piece hot press gluing machine in CN113172983A. There is no need to set up a transfer bracket structure for single-piece conveying. The working principle of this technical solution is to convey the materials to be glued (door panels) into each gluing space of the gluing device in turn through an external input device for objects to be glued. The materials to be glued in the gluing space are heated by the pressing plate and under the pressure of the load box above. After gluing is completed, the glued material is then transported to an external device for outputting the glued object. The present invention outputs the material through a conveyor belt structure wound on the pressing plate. There is a gap between the conveyor belt structure wound on the lowest pressing plate and the bottom of the gluing device for the conveyor belt to drive. Taking the material on the lowest pressing plate that needs to be output as an example, during output, since the material is in contact with the upper pressing plate on the top and is pressed by a load box on the top, the positioning structure selects the gluing space of this layer and lifts up all the pressing plates above the gluing space so that the pressing plates are not in contact with the top. The conveyor belt structure wound on this layer of pressing plates can drive and output the material, and the external device for outputting the glued object on the other side of the gluing device The output platform in the middle reaches the corresponding position of the layer of plywood under the action of the output lifting device, and receives the finished gluing material output by the conveyor belt structure for storage or backward transmission for edge pressing or other processes. Taking the material on the plywood layer above the lowest layer of plywood as an example, when the finished gluing material on the layer of plywood needs to be output, the positioning mechanism lifts all the plywood and the load box above the plywood where the material is located, so that the finished gluing material on the layer of plywood does not contact with other objects above. Since there is material under the layer of plywood, the lower layer of plywood needs to be slightly lifted. The layer of plywood is slightly lifted under the action of the second positioning structure so that the plywood set on the layer of plywood can be The conveyor belt structure can transmit and output the finished gluing material to the output platform in the finished gluing object output device. The output platform arrives at the corresponding position of the layer of plywood under the action of the output lifting device to receive the finished gluing material for storage or backward transmission for edge pressing or other processes. The present invention realizes the mode that the conveyor belt structure on the plywood obliquely inputs the material to be glued and outputs the finished gluing material by arranging the conveyor belt structure and the second positioning structure on each plywood. The prior art such as CN106113169B matches the input of the material to be glued and the output device of the finished gluing object by lifting the gluing device. The gluing device is heavy and has a slow lifting speed. The mode of the present invention significantly improves the production efficiency.

Both sides of the conveyor belt 141 in the width direction are smaller than the width of the pressing plate 11 to form a positioning area 142 in contact with the second positioning structure. Opposite mounting seats 15 are installed at both ends of the pressing plate 11. A rotatable tensioning shaft 16 is passed through the two opposite mounting seats 15.

A tensioning adjustment structure is provided between one side of the mounting seat 15 and the tensioning shaft 16.

[0044] The belt driving source is set as a servo motor, which has higher precision. Since it is necessary to ensure that the conveyor belt can be driven by the belt driving source when the pressing plate is lifted by the second positioning mechanism, the conveyor belt cannot be set as wide as the pressing plate, but needs to leave a distance to form a positioning area to contact the second positioning structure, so as to ensure that the conveyor belt can be normally driven when the second positioning structure lifts the pressing plate. Since the gluing device of the gluing machine is very large, the parts on it are often transported to the site for assembly during transportation. Therefore, the tension adjustment structure set up allows the assemblers to adjust the belt tension on site according to needs, thereby improving assembly efficiency and versatility.

[0048] The plug-in plate assembly is fixedly mounted on the lifting frame through the plug-in plate mounting seat. When the gluing device needs to select a certain pressing space, the plug-in plate assembly is inserted into the corresponding pressing space.

[0050] The plug-in board assembly is driven by a plug-in board driving cylinder, which has a fast response speed and a stable structure. The plug-in board guide structure can guide the movement trajectory of the plug-in board when it is extended, improve the straightness of the plug-in board after it is extended, and avoid the problem of poor contact between the plug-in board and the pressing plate, which leads to a short service life of the plug-in board;

[0051] The plug-in board guide structure includes a guide sleeve 1033 fixedly connected to the plug-in board mounting seat 1032 at one end, and one end of the guide sleeve 1033 passes through the lifting frame 103 and extends toward the plug-in board 10311 and surrounds the plug-in board 10311 to form a plug-in board guide cavity 10331. The plug-in board 10311 can be extended out of the plug-in board guide cavity 10331 under the action of the plug-in board driving cylinder 10312;

[0052] One side of the guide sleeve is first connected to the plug-in board mounting seat, and the other side is fixedly mounted on the lifting frame to improve the integration. By covering the plug-in board in the guide cavity of the guide sleeve, on the one hand, it can protect the plug-in board. On the other hand, the shape of the guide cavity is adapted to the plug-in board, which plays a role in guiding the extension direction of the plug-in board.

[0053] The second positioning structure includes a hanging platform seat 104, a notch 1041 matching the thickness of the lifting frame 103 is provided on one side of the hanging platform seat 104, a hanging platform installation platform 1034 for installing the hanging platform seat 104 is provided on the lifting frame 103, the hanging platform seat 104 is installed on the hanging platform installation platform 1034 through a fastener (not shown in the figure) and is clamped to the lifting frame 103 through the notch 1041, a hanging platform through groove 1042 is provided in the hanging platform seat 104, the hanging platform seat 104 is connected to a hanging platform cylinder 1043 at one end of the hanging platform through groove 1042, and a hanging platform plate (not shown in the figure) matching the shape of the hanging platform through groove 1042 is connected to the cylinder rod of the hanging platform cylinder 1043, and the hanging platform plate can pass through the hanging platform through groove 1042 under the action of the hanging platform cylinder 1043;

[0054] The second positioning structure and the positioning structure are staggered, and the specific distance control is that when the plug-in board assembly extends into the pressing space, the hanging table plate of the second positioning structure can lift the lower pressing plate under the pressing plate under the pressing space, and one end of the hanging table seat is installed on the hanging table installation platform through a fastener and is clamped on the lifting frame through a notch, so that it is firmly fixed. At the same time, the hanging table seat also plays a role in protecting the hanging table plate, and the hanging table through groove is set to be adapted to the shape of the hanging table plate and plays a guiding role for the hanging table plate;

[0055] A plurality of relatively arranged lifting guide structures 105 are arranged on the outer periphery of the lifting frame 103;

[0056] Since the lifting frame needs to bear the weight of multiple parts such as adhesives and pressed plates during the lifting process, it is necessary to ensure its stability during the lifting process. Otherwise, uneven force may be applied to both sides of the lifting frame, resulting in unstable operation. The utility model provides multiple sets of relatively arranged lifting guide structures around the lifting frame to ensure smooth lifting of the lifting frame, improve the stability of the device, and thus increase the service life of the device.

[0057] The lifting guide structure 105 includes an outer guide seat 1051 installed on one side of the lifting frame 103 and an inner guide seat 1052 installed on the other side of the lifting frame 103 and arranged opposite to the outer guide seat 1051. One end of each of the outer guide seat 1051 and the inner guide seat 1052 is provided with a rotatable guide wheel 1053. The outer guide seat 1051 and the inner guide seat 1052 are connected via a rotatable connecting shaft 1054.

[0058] The guide wheels arranged on the relatively arranged outer guide seat of the lifting frame and the inner guide seat of the lifting frame are used to guide the inner and outer sides of the lifting frame respectively, and the synchronization degree is high. The inner guide seat of the lifting frame is connected with the outer guide seat of the lifting frame by a rotatable connecting shaft, which ensures the synchronization of the inner guide seat of the lifting frame and the outer guide seat of the lifting frame. In order to further improve the synchronization degree, a lifting synchronization gear 1055 can be installed at the position where the connecting shaft 1054 is located between the inner guide seat 1052 of the lifting frame and the outer guide seat 1051 of the lifting frame. The lifting synchronization gear 1055 shown in the figure is only a schematic diagram on the lifting synchronization rack 1056. A lifting synchronization rack 1056 meshing with the lifting synchronization gear 1055 is arranged on the body of the gluing device to further improve stability. Of course, a synchronization shaft 106 can also be arranged at the end of the lifting frame 103 away from the driving source 101, and synchronization gears 1061 are arranged at both ends of the synchronization shaft 106. A synchronization rack meshing with the synchronization gear 1061 is arranged on the body of the gluing device to further improve stability.

[0059] The driving source 101 is a cylinder;

[0060] The driving source is set as an oil cylinder to improve the versatility of the driving source. Of course, the driving source can also be set as a driving motor or a driving cylinder, but considering the weight of the parts of the gluing device, the lifting speed and other factors, setting it as a driving oil cylinder is the most preferred solution;

[0061] The beneficial effects of the utility model are as follows: belts are arranged on each layer of the plywood for conveying, and the conveying efficiency is high. The positioning structure and the second positioning structure arranged on the lifting frame can synchronously lift the pressing space to be selected and the pressing plate under the pressing space, and cooperate with the conveyor belt structure arranged on each pressing plate to achieve active output of the gluing material on each layer. The driving source is arranged on the ground on both sides of the machine body, which reduces the design requirements of the machine body and improves the installation and maintenance efficiency.
