Description

Technical Field

[0001] This utility model relates to the field of bookbinding technology, specifically to a bookbinding material bonding device. Background Technology

[0002] During the book printing process, the cover needs to be bound, such as by attaching a crystal plate, which can improve the durability of the book cover and make it more beautiful.

[0003] Current bookbinding material bonding operations are based on a structure consisting of robotic arms, conveyors, lifting supply boxes, and electric heating plates mounted at the lower end of lifting cylinders. These components work in conjunction with bookbinding materials containing adhesive to complete the bonding process. Specifically, one robotic arm continuously retrieves books from the lifting supply box and places them on the conveyor, while another robotic arm retrieves bookbinding materials from the lifting supply box and places them on the book covers. Then, the lifting cylinder drives the electric heating plate to press down on the bookbinding materials once, melting the adhesive to secure the cover to the bookbinding materials.

[0004] The method of heating after transferring the binding material requires a certain amount of heat transfer time, and if the heating temperature is too low, the adhesion will be weak. The transfer speed needs to be coordinated with the heating time, resulting in a slow overall operation speed.

[0005] Therefore, in order to solve the above problems, a bookbinding material bonding device is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a binding material bonding device to shorten the operation cycle and improve bonding efficiency, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A bookbinding material bonding device includes a conveyor, a gantry frame fixedly mounted on the upper side of the conveyor frame, a control cabinet mounted on one side of the gantry frame, and a moving mechanism mounted on the other side of the gantry frame. A vacuum nozzle is mounted on the lower side of the moving mechanism via a connecting seat. An insulation box is mounted on the upper part of the conveyor via an elastic mechanism. The front and lower sides of the insulation box are open. A groove for the connecting seat to pass through is opened on the top of the insulation box. An electric heating plate is fixedly mounted inside the insulation box. Roller belts for abutting against the upper side of the insulation box are fixedly mounted on the left and right sides of the connecting seat.

[0008] Specifically, the vacuum nozzles are four in a rectangular array.

[0009] Specifically, there are three heating plates arranged horizontally, with gaps between adjacent heating plates for the vacuum nozzle to pass through.

[0010] Specifically, the diameters of the two rear rollers in the roller belt component decrease sequentially.

[0011] Specifically, the elastic mechanism includes a limiting block, a linear bearing, a guide rod, and a spring. Linear bearings are fixedly installed at the four corners of the insulation box. Two bases are fixedly installed on the front and rear sides of the conveyor frame. A guide rod is fixedly installed on the upper side of each base. The guide rod is inserted into the aligned linear bearing. A spring is sleeved on each guide rod. The spring abuts against the base and the linear bearing. A limiting block is fixedly installed at the upper end of each guide rod, and the limiting block is located above the linear bearing.

[0012] Specifically, the moving mechanism includes a lifting cylinder, a rodless cylinder, and a bolt assembly. The rodless cylinder is horizontally fixed on the side wall of the gantry, and the lifting cylinder is vertically fixed on the slide of the rodless cylinder. Through holes are provided at the four corners of the output platform of the lifting cylinder, and the through holes and the connecting seat are connected and assembled by the bolt assembly.

[0013] Specifically, rubber blocks are uniformly fixedly installed along the edges of the front and rear sides of the conveyor belt, and rubber ribs are uniformly fixedly installed on the surface of the conveyor belt, with the rubber ribs located between the front rubber blocks and the rear rubber blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By combining the moving mechanism and the vacuum nozzle, the actions of picking up the binding material and lowering the heating plate can be integrated into one, simplifying the operation process; The flexible mechanism works in conjunction with the insulation box. When the vacuum nozzle transfers the binding material, the roller belt presses down on the insulation box, causing the heating plate to descend along with the binding material. The adhesive can be melted during the transfer process, eliminating the need for additional heat transfer time and significantly reducing operation time. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example content: Please see Figure 1 A bookbinding material bonding device is provided, including a conveyor 1. The conveyor 1 is an existing device with a frame, a conveyor belt, a geared motor and a rotating roller. The frame supports other components. During operation, the geared motor drives a rotating roller and, in cooperation with other rotating rollers, can circulate the conveyor belt to continuously transport books placed on the conveyor belt.

[0019] A gantry 3 is fixedly installed on the upper side of the frame of the conveyor 1. A control cabinet 2 is installed on one side of the gantry 3, and a moving mechanism 4 is installed on the other side of the gantry 3. The gantry is used to support the upper components and span the working area of ​​the conveyor 1 to ensure that the book conveying channel below is not obstructed.

[0020] A vacuum nozzle 6 is installed on the lower side of the moving mechanism 4 via a connecting seat 12. When in use, the vacuum nozzle 6 is connected to an external vacuum generator via an air pipe. The moving mechanism 4 can move the vacuum nozzle 6 in the horizontal and vertical directions to complete the operation of taking out the binding material from the lifting supply box and placing it on the book.

[0021] An insulated box 11 is installed above the conveyor 1 via an elastic mechanism 7. The insulated box 11 is an existing structure of a box body and an insulation layer (such as polyurethane foam board) to form a heat insulation barrier and reduce heat loss. The front and lower sides of the insulated box 11 are open, and the top of the insulated box 11 has a groove 13 for the connecting seat 12 to pass through. The elastic mechanism 7 gives the insulated box 11 an upward restoring force. The structure of the insulated box 11 does not affect the connecting seat 12, the vacuum nozzle 6, and the transfer path of the packaging material.

[0022] An electric heating plate 10 is fixedly installed inside the heat preservation box 11. The electric heating plate 10 is used to heat the binding material, thereby melting the adhesive at the bottom of the binding material through heat conduction.

[0023] Roller belts 5 for abutting the upper side of the insulation box 11 are fixedly installed on the left and right sides of the connecting seat 12. The roller belts 5 are existing components with a U-shaped frame and rollers. The rollers are evenly rotated and installed in the U-shaped frame. When the roller belts 5 move horizontally backward, they can roll and contact the upper side of the insulation box 11, reducing the friction during contact. When the roller belts 5 move downward with the connecting seat 12, they can press down on the insulation box 11, causing the insulation box 11, the heating plate 10 and the binding material to fall together. The adhesive can be melted during the transfer process, reducing the operation time.

[0024] Adhesives are often made of hot melt adhesives with a melting point range of 80-110℃, such as EVA (ethylene-vinyl acetate) based hot melt adhesives. These adhesives have the characteristics of melting quickly and curing after cooling.

[0025] Specifically: The vacuum nozzles 6 consist of four nozzles arranged in a rectangular array. This layout ensures that the nozzles 6 are evenly spaced and aligned, avoiding offset or overlap during adsorption. Simultaneously, the four nozzles 6 working together create a distributed adsorption force field.

[0026] The number of heating plates 10 is three, horizontally distributed, with a heating temperature of 80-150℃. The design of three heating plates can expand the heating coverage area and improve temperature uniformity. There is a gap between adjacent heating plates 10 for the vacuum nozzle 6 to pass through. The gap design avoids the heating plates 10 from blocking the movement path of the nozzle 6, and at the same time avoids direct contact between the nozzle 6 and the high-temperature heating plates 10, reducing heat loss or the risk of nozzle aging.

[0027] Please see Figure 3 The structure of roller belt 5: The diameters of the two rear rollers in the roller belt 5 decrease sequentially. This difference in diameter facilitates the rearward movement of the roller belt 5, allowing it to travel more smoothly to the upper side of the insulation box 11 and reducing the risk of jamming.

[0028] Please see Figure 2 The structure of elastic mechanism 7: The elastic mechanism 7 includes a limiting block 71, a linear bearing 72, a guide rod 73, and a spring 74. A linear bearing 72 is fixedly installed at each of the four corners of the insulation box 11. The linear bearing 72 is vertically arranged. Two bases are fixedly installed on the front and rear sides of the conveyor 1 frame. A guide rod 73 is fixedly installed on the upper side of each base. The guide rod 73 is inserted into the aligned linear bearing 72. A spring 74 is sleeved on each guide rod 73. The spring 74 abuts against the base and the linear bearing 72. A limiting block 71 is fixedly installed on the upper end of each guide rod 73, and the limiting block 71 is located above the linear bearing 72.

[0029] Four linear bearings 72 can move up and down stably along the guide rod 73, while the limiting block 71 can prevent the linear bearings 72 from disengaging from the guide rod 73. The elastic coefficient of the spring 74 needs to be selected in combination with the expected compression amount and reset speed requirements to ensure that it can store enough potential energy when subjected to downward external force and release it stably after the external force disappears, pushing the heat preservation box 11 to reset upward.

[0030] Please see Figure 4 The structure of the moving mechanism 4: The moving mechanism 4 includes a lifting cylinder 41, a rodless cylinder 42, and a bolt group 43. The rodless cylinder 42 is horizontally fixed on the side wall of the gantry 3, and the lifting cylinder 41 is vertically fixed on the slide of the rodless cylinder 42. Through holes are provided at the four corners of the output platform of the lifting cylinder 41, and the through holes and the connecting seat 12 are connected and assembled by the bolt group 43.

[0031] The slide of the rodless cylinder 42 can reciprocate linearly in the front-back direction, and the lifting cylinder 41 can drive the connecting seat 12 to move up and down, forming a two-stage motion structure of horizontal and vertical. The position of the connecting seat 12 on the output platform can be easily adjusted by the connection method of the bolt group 43 to meet the thickness requirements of different binding materials, and it is easy to disassemble during maintenance.

[0032] Rubber blocks 8 are evenly fixedly installed on the front and rear sides of the conveyor belt of the conveyor 1 along the edge. Rubber ribs 9 are evenly fixedly installed on the surface of the conveyor belt of the conveyor 1, and the rubber ribs 9 are located between the front rubber block 8 and the rear rubber block 8.

[0033] The rubber stop 8 and the rubber rib 9 form multiple storage slots for placing books. The storage slots can be moved in a cyclical manner, which is conducive to the precise placement of books and thus improves the accuracy of the bonding operation.

[0034] Control cabinet 2 is a standardized industrial control device with a human-machine interface, programmable logic controller, relay module and redundant power supply system. Control cabinet 2 is used to coordinate the operation of electrical components such as conveyor 1, rodless cylinder 42, lifting cylinder 41, vacuum nozzle 6 and heating plate 10 to ensure continuous operation.

[0035] The working principle of this embodiment: During operation, the conveyor 1 continuously positions the books through the placement groove formed between the rubber ribs 9 and the rubber stops 8.

[0036] The rodless cylinder 42 in the moving mechanism 4 drives the lifting cylinder 41 to move horizontally. The lifting cylinder 41 drives the vacuum nozzle 6 to move up and down, so that the vacuum nozzle 6 can grab the binding material from the lifting supply box and place it on the book cover. During the process, the roller belt 5 on both sides of the connecting seat 12 presses down the heat preservation box 11, overcoming the elastic force of the spring 74 of the elastic mechanism 7, so that the heat preservation box 11 and the internal electric heating plate 10 descend synchronously with the binding material. During the transfer process, the adhesive at the bottom of the binding material is directly heated, so as to achieve the purpose of heating while transferring.

[0037] After placement, roller belt 5 moves upward, and spring 74 pushes the insulation box 11 to reset.

[0038] This device integrates material picking, transfer, and heating bonding actions, avoiding the waiting time of separate heating after transfer in traditional processes, greatly shortening the operation cycle, improving bonding efficiency and quality, and avoiding weak bonding caused by insufficient heating.
