The main structure of the machine includes a frame, an oil cylinder, a pressing plate, and a material pressing cylinder. The oil cylinder is used to push the pressing plate to extend towards the material pressing barrel, and the hot melt adhesive in the material pressing barrel is pressed out.

[0003] There is a new type of hot melt adhesive hydraulic discharging machine. Rollers and threaded rods are respectively arranged at the four corners of the bottom of the bottom plate. While facilitating the movement of the equipment, by clockwise rotating the threaded rods, the bottom ends of the threaded rods extend downward through the mounting plates, and the positioning plates provided at the bottoms of the threaded rods are in contact with the ground to achieve the equipment positioning effect.

[0004] However, in practice, when positioning the equipment, it is necessary to manually turn the threaded rods at the four corners respectively to make the positioning plates contact the ground in order to achieve a sufficiently good positioning effect. However, this operation is time-consuming and laborious, affecting the equipment positioning efficiency. Summary of the Utility Model

[0005] In order to solve the above technical problems, a new type of hot melt adhesive hydraulic discharging machine is provided, which solves the problem that in the prior art, when positioning the equipment, it is necessary to manually turn the threaded rods at the four corners respectively to make the positioning plates contact the ground in order to achieve a sufficiently good positioning effect, but the operation is time-consuming and laborious.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a new type of hot melt adhesive hydraulic discharging machine, including a bottom plate and a material pressing cylinder arranged on the top surface of the bottom plate. The top surface of the material pressing cylinder is open. An arch-shaped large support frame is arranged above the material pressing cylinder. The two ends of the large support frame are respectively fixed on both sides of the top surface of the bottom plate. An oil cylinder is installed on the top surface of the large support frame. The telescopic rod of the oil cylinder slides into the large support frame and is fixed with a pressing plate. The outer wall of the pressing plate is slidably connected with the inner wall of the open mouth of the material pressing cylinder. Rollers are respectively installed at the four corners of the bottom surface of the bottom plate. The characteristics are that: synchronous positioning mechanisms are arranged on both the front and rear sides of the bottom plate, and a synchronous acting mechanism is arranged between the two groups of synchronous positioning mechanisms;

[0007] The synchronous positioning mechanism includes two small support frames symmetrically and fixedly arranged in an inverted L shape on the top surface of the bottom plate, a rotating rod rotatably arranged in the inner wall of the top end of the small support frame in a T shape, and a threaded sleeve slidably arranged below the rotating rod. Pulley wheels are fixedly sleeved on the rod bodies of the two rotating rods, and a belt is connected in a transmission manner between the two pulley wheels. A long screw rod is fixed at the bottom end of the rotating rod, and the end of the long screw rod is threadedly inserted into the inner side of the threaded sleeve. A through groove corresponding to the threaded sleeve is penetrated and opened on the top surface of the bottom plate, and the bottom end of the threaded sleeve penetrates through the through groove and is detachably provided with a positioning plate.

[0008] Preferably, the synchronous acting mechanism includes a fixed block fixedly arranged on the inner wall of one side of the pressing cylinder, a rotating shaft horizontally rotatably arranged in the inner wall of the fixed block, and two gears respectively fixed at both ends of the rotating shaft. A second satellite gear is engaged below one of the gears, and the second satellite gear is fixed on the top surface of one of the rear rotating rods. A first satellite gear is engaged above the other gear, a connecting shaft is fixed at the center of the bottom surface of the first satellite gear, and the connecting shaft is fixed on the top surface of one of the front rotating rods.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] Through the cooperative setting of the synchronous positioning mechanism and the synchronous acting mechanism, the rotation of the connecting shaft and the gear can be driven by the first satellite gear. The connecting shaft drives the rotation of the corresponding long screw rod through one of the front rotating rods, and drives the corresponding threaded sleeve. However, the threaded sleeve is restricted by the limiting rod and the sliding groove, so that it can only move downward along the through groove, and finally realizes the synchronous lifting and lowering of the four threaded sleeves. In this way, it can replace the operation in the prior art that requires manual screwing of the threaded rods at the four corners respectively to position the equipment.

Specific embodiments

[0018] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0019] Referring to Figure 1 、 Figure 2 And Figure 3 As shown in the figure, a new type of hot melt adhesive hydraulic discharging machine includes a bottom plate 3 and a pressure cylinder 1 arranged on the top surface of the bottom plate 3. The top surface of the pressure cylinder 1 is open. Above the pressure cylinder 1, there is a large support frame 4 in the shape of an arch. The two ends of the large support frame 4 are respectively fixed on both sides of the top surface of the bottom plate 3. An oil cylinder 2 is installed on the top surface of the large support frame 4. The telescopic rod of the oil cylinder 2 slides into the large support frame 4 and is fixed with a pressure plate 5. The outer wall of the pressure plate 5 is slidably connected with the inner wall of the open end of the pressure cylinder 1. Rollers 6 are respectively installed at the four corners of the bottom surface of the bottom plate 3. Synchronous positioning mechanisms are provided on both the front and back sides of the bottom plate 3, and a synchronous acting mechanism is provided between the two groups of synchronous positioning mechanisms;

[0020] Through the arrangement of the pressure cylinder 1, the oil cylinder 2 and the pressure plate 5, when hydraulic processing of the hot melt adhesive is required, the pressure plate 5 can be driven to move up and down inside and outside the open end of the pressure cylinder 1 by the telescopic rod of the oil cylinder 2. During this process, the large support frame 4 provides support for the oil cylinder 2, so that the hot melt adhesive in the pressure cylinder 1 can be intermittently extruded. The rollers 6 installed at the four corners of the bottom surface of the bottom plate 3 are for facilitating the movement of the main body of the device.

[0021] Further, referring to Figures 1 to 3As shown, it should be noted that the synchronous positioning mechanism includes two small support frames 7 symmetrically fixed in an inverted L shape on the top surface of the bottom plate 3, a rotating rod 11 rotatably arranged in an inner wall of the top end of the small support frame 7 in a T shape, and a threaded sleeve 8 slidably arranged below the rotating rod 11. Pulley wheels are fixedly sleeved on the rod bodies of the two rotating rods 11, and a belt is drivingly connected between the two pulley wheels. A long screw rod 9 is fixed at the bottom end of the rotating rod 11, and the end of the long screw rod 9 is threadedly inserted into the inner side of the threaded sleeve 8. Moreover, a through groove corresponding to the threaded sleeve 8 is penetrated and opened on the top surface of the bottom plate 3. The bottom end of the threaded sleeve 8 penetrates through the through groove and is detachably provided with a positioning plate 10. A short screw rod 18 is fixed at the center of the top surface of the positioning plate 10, and the short screw rod 18 is threadedly inserted into the inner side of the threaded sleeve 8. Limiting rods 19 are fixed on both sides of the threaded sleeve 8, and sliding grooves adapted to the limiting rods 19 are opened on the inner wall of the through groove;

[0022] The synchronous action mechanism includes a fixed block 13 on an inner wall of one side of the fixed pressing cylinder 1, a rotating shaft 15 horizontally rotatably arranged in the inner wall of the fixed block 13, and two gears 14 respectively fixed at both ends of the rotating shaft 15. A second satellite gear 17 is engaged below one of the gears 14, and the second satellite gear 17 is fixed on the top surface of one of the rear rotating rods 11. A first satellite gear 12 is engaged above the other gear 14, a connecting shaft 16 is fixed at the center of the bottom surface of the first satellite gear 12, and the connecting shaft 16 is fixed on the top surface of one of the front rotating rods 11. The two rotating rods 11 are in the same column, and a handle is fixed at the edge of the top surface of the first satellite gear 12;

[0023] Through the cooperative setting of the synchronous positioning mechanism and the synchronous acting mechanism, when positioning the discharging machine, the first satellite gear 12 can be driven to rotate by the handle. The rotation of the first satellite gear 12 simultaneously drives the rotation of the connecting shaft 16 and one of the gears 14. The rotation of the connecting shaft 16 drives the rotation of one of the rotating rods 11 on the front side of the bottom plate 3. The rotation of one of the rotating rods 11 drives the rotation of the corresponding long screw rod 9. The rotation of the long screw rod 9 drives the corresponding threaded sleeve 8. However, the threaded sleeve 8 is restricted by the limiting rods 19 on both sides and the sliding grooves in the inner wall of the bottom plate 3, resulting in the threaded sleeve 8 only being able to move downward along the corresponding through slots on the bottom plate 3. And the rotation of one of the rotating rods 11 also drives the synchronous rotation of the other rotating rod 11 on the same side through the pulleys and belts on the rod body. Similarly, the rotation of the other rotating rod 11 drives the corresponding threaded sleeve 8 to move downward along the corresponding through slot, resulting in the synchronous lifting and lowering of the two threaded sleeves 8 on the front side. At the same time, the rotation of the gear 14 drives the rotation of the rotating shaft 15. During this process, the fixed block 13 plays a supporting role for the rotating shaft 15. The rotation of the rotating shaft 15 drives the rotation of the other gear 14. The rotation of the other gear 14 drives the rotation of the second satellite gear 17. The rotation of the second satellite gear 17 drives the rotation of one of the rotating rods 11 on the rear side of the bottom plate 3. Similarly, when one of the rotating rods 11 on the rear side drives the corresponding threaded sleeve 8 on the rear side to descend, it also drives the synchronous descent of the other threaded sleeve 8 on the rear side through the pulley, and finally realizes the synchronous lifting and lowering of the four threaded sleeves 8. The descent of the threaded sleeve 8 drives the descent of the positioning plate 10 until it contacts the ground, and then the positioning plate 10 is used to realize the positioning and fixing of the whole discharging machine. And the positioning plate 10 and the threaded sleeve 8 are detachably connected through the short screw rod 18. In this way, when the positioning plate 10 is worn after long-term use, the positioning plate 10 can be replaced. In this way, it can replace the operation in the prior art that requires manual screwing of the threaded rods at the four corners respectively to position the equipment when positioning the equipment.
