[0002] At present, hot pressing and bonding machines are widely used in the sponge bonding of seating furniture. The sponge bonding process of seating furniture is an important process in the manufacturing process of seating furniture. Multiple layers of sponges are bonded with glue and used for the seat surface, backrest, headrest of seats, and elastic pads of objects such as sofas and beds.
[0003] During the use of a hot pressing and bonding machine, employees need to perform operations such as loading and unloading materials beside the machine. In this process, they may be injured by the operating machine. Most machines on the market are only equipped with an emergency stop button to stop the machine, but it cannot help the operators quickly break free from the machine and reduce injuries. Content of the Utility Model
[0004] Technical problems to be solved.
[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a descent mechanism, an operating table and a hot pressing and bonding device capable of coping with accidental machine injuries. By arranging a cylinder and a bracket under one end of the operating table, the cylinder will pull the bracket to move, causing the bracket to tilt, so that one end of the operating table supported by the bracket descends, enabling the operating table to move away from the hot pressing and bonding machine or other machines above, making it easier for the operator to break free from the machine and reducing the injuries suffered by the operator.
[0006] To solve the above problems, the utility model adopts the following technical solutions.
[0007] A descent mechanism capable of coping with accidental machine injuries, the machine is arranged above one side of the operating table, the operating table is installed on a frame, the descent mechanism includes a movable bracket arranged under the machine side of the operating table, a cylinder for driving the bracket to tilt, and a control system for controlling the movement of the cylinder, the cylinder is connected between the bracket and the frame; when the cylinder is not started, the bracket normally supports the operating table; when coping with accidental machine injuries, the cylinder is started, and the cylinder drives the bracket to tilt, so that the height of the upper end of the bracket decreases, and the machine side of the operating table descends accordingly. It is beneficial for the operator accidentally involved in the operating table to quickly break away from the machine and avoid more injuries.
[0008] Furthermore, the upper end of the bracket is movably connected to the operating table, and the lower end of the bracket abuts against the frame. Using the movable connection method, the structure is flexible and convenient for installation and maintenance.
[0009] Further, the connection mode of the upper end of the bracket and the operating table is a connection mechanism. The connection mechanism includes a first connecting piece and a second connecting piece that are hinged to each other. One end of the first connecting piece away from the second connecting piece is fixedly connected to the operating table, and one end of the second connecting piece away from the first connecting piece is fixedly connected to the bracket. The lower end of the bracket abuts against the frame. The rotation between the first transfer table and the bracket is realized through the connection mechanism, which can make the tabletop descend more quickly, avoiding further injury to the operator being involved.
[0010] Further, the upper end of the bracket is slidably connected to the operating table, the lower end of the bracket is slidably connected to the frame, and the cylinder is connected to the upper end or the lower end of the bracket. The ability to slide up and down can accelerate the process of the bracket changing from a vertical state to an inclined state, enabling the end of the operating table supported by the bracket to quickly descend, and releasing the accidentally injured operator.
[0011] Further still, a limiting groove is provided at the connection between the operating table and the bracket. The upper end of the bracket can slide within the limiting groove. A support rod is provided at the lower end of the bracket, and a groove is provided on the support rod. The lower end of the bracket can slide within the groove. Limiting the movement trajectory of the bracket through the groove can prevent the bracket from colliding with other components during movement, improving the stability and safety of the device.
[0012] An operating table capable of coping with accidental machine injuries, the operating table includes the above-mentioned emergency descent mechanism, and also includes a transfer table. One end of the transfer table is installed on the frame, and the other end is connected to the emergency descent mechanism. The transfer table can transfer objects to be processed under the machine.
[0013] Further, the transfer table includes a second transfer table at the end away from the machine, a first transfer table at the end close to the machine, and a sliding connection block provided at the connection between the second transfer table and the first transfer table. The second transfer table operating table is installed on the frame. One end of the first transfer table away from the machine is connected to the second transfer table through the sliding connection block, and one end of the first transfer table close to the machine is connected to the emergency descent mechanism. The operating table is divided into two parts, one part is relatively fixed and the other part is relatively movable. While retaining the function of the operating table to prevent the accidentally injured operator from being involved in the machine by emergency descent, the stability and safety of the device are improved. The sliding connection block rotatably connects the first transfer table and the second transfer table and supports one end where the first transfer table and the second transfer table are connected.
[0014] A hot pressing and bonding device capable of coping with accidental machine injuries, including the above-mentioned operating table, and also includes a hot pressing mechanism. The hot pressing mechanism is located at one end of the first transfer table away from the second transfer table. The hot pressing and bonding of the object to be bonded is completed through the joint operation of the hot pressing mechanism and the transfer table.
[0015] Further, the hot pressing mechanism is installed on the frame. The hot pressing mechanism includes a hot pressing component unit and a rotating component for driving the hot pressing component unit to rotate. The hot pressing component unit includes a conductive shaft, a turntable, a heating element, a hot pressing head, a connecting block, and a driven wheel. The turntable includes a conductive ring and a non-conductive ring, and the non-conductive ring is connected in parallel to the conductive ring. The conductive ring is rotatably sleeved on the conductive shaft. The hot pressing head is fixedly protruded from the edge of the non-conductive ring of the turntable. The heating element is connected to the hot pressing head to heat it. Both ends of the conductive shaft are fixedly sleeved on the connecting block. The driven wheel is rotatably sleeved on the conductive shaft and is fixed to the turntable. The rotating component includes a rotating motor, a rotating shaft that rotates synchronously with the output shaft of the motor through a first synchronous belt, a rotating wheel fixedly sleeved on the rotating shaft, and a second synchronous belt connecting the rotating wheel and the driven wheel to rotate synchronously. The objects to be bonded are often simple objects that do not require full bonding, such as the seat surface, backrest, and headrest of a seat, as well as the elastic pads of objects such as sofas and beds. This hot pressing bonding device can perform equally spaced dot-type hot pressing bonding on them, ensuring the bonding quality while greatly improving the bonding efficiency. Moreover, during the bonding process, the pressure generated by the hot pressing mechanism on the conveyor table is small, and the safety is high. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the utility model belong to the scope of protection of the utility model.
[0037] A forced landing mechanism that can deal with accidental damage to the machine, please refer to Figure 1 The forced landing mechanism includes a movable bracket 801 arranged below the machine side of the operating table, a cylinder 8 driving the bracket 801 to tilt, and a control system for controlling the movement of the cylinder 8. The cylinder 8 is connected between the bracket 801 and the frame; when the cylinder 8 is not started, the bracket 801 normally supports the operating table; when it is necessary to deal with accidental damage to the machine, the cylinder 8 is started, and the cylinder 8 drives the bracket 801 to tilt, so that the upper end of the bracket 801 drops in height, and the machine side of the operating table lands accordingly. Specifically, there are two chambers in the cylinder 8, which are separated by a piston plate. The bracket 801 is connected to the piston plate of the cylinder 8. By controlling the air pressure in the two chambers, the piston plate moves in the cylinder 8. At the same time, the cylinder 8 drives the bracket 801 to move and tilt the bracket 801, and the vertical height of the bracket 801 becomes lower. The operating table relies on the bracket 801 to support one end to complete the forced landing.
[0038] Please see Figure 1 Preferably, the bracket is connected to the piston plate through a piston rod 804, one end of the piston rod 804 is fixedly connected to the piston plate, and the other end is rotatably connected to the bracket 801. The piston plate drives the piston rod 804 to move, and the piston rod 804 drives the bracket to move to complete the forced landing process. Example 1
[0039] Please see Figure 2 The bracket 801 is movably connected to the operating table, and the lower end of the bracket 801 is against the frame. When the piston rod 804 pulls the bracket 801, the connection point between the bracket 801 and the piston rod 804 moves, and the connection point between the piston rod 804 and the bracket 801 and the connection point between the operating table and the bracket 801 are no longer on the same vertical line. The bracket 801 becomes tilted, so that the table top of one end of the operating table supported by the bracket 801 drops, and the connection position between the cylinder 8 and the bracket 801 is preferably the lower end of the bracket.
[0040] Please see Figures 3 - 5, the way of movably connecting the bracket 801 and the operating table 22 is to set a first connecting member 802 and a second connecting member 803 that are hinged to each other.
