A spiral protrusion is provided on the outer wall of the pressing shaft, and the inclination angle of the spiral protrusion is greater than 45° and less than 60°.

[0007] Further preferably, the turntable one is composed of a turntable, a shaft, a gear and a handle. The protection box wraps around the gears of the four threaded cylinders and is rotatably connected to the threaded cylinders. A through hole is provided on one side surface of the protection box and is connected to the shaft of the turntable one. The teeth of the turntable one are in transmission connection with the toothed belt at the threaded cylinder. One side of the tops of two support screws is connected with a side plate, and two parallel slide rods are provided between the two side plates.

[0008] Further preferably, two sliders are connected to both sides of the lower surface of the skateboard. The sliders are slidably connected to the slide rods. In the middle of one side of the lower surface of the skateboard, a threaded block is connected. On one side of the threaded block, there are fixed blocks connected to both sides of the lower surface of the skateboard. A regulating cylinder is rotatably connected between the two fixed blocks. The shaft of the first turntable passes through the side plate and the fixed block and is connected to the middle gear of the regulating cylinder through the teeth at one end.

[0009] Further preferably, the two pressing shafts are installed in parallel. Two transmission grooves are provided on the outer walls of the pressing shafts. Gears coaxial with the pressing shafts are provided in the transmission grooves. The two pressing shafts on the same side are rotatably connected to a support box. The support box wraps around the gears and the toothed belt. A transmission shaft is rotatably connected to the bottom end of the support box. The two support boxes are connected by a connecting plate. The inner surfaces of the connecting plates of the two pressing assemblies are both threadedly connected to the two ends of the inner wall of the regulating cylinder through threaded rods.

[0010] Further preferably, a gear set is provided on the upper surface of the protection box. A motor is provided at one end of the gear set. The gear set is connected to the middle gear of the transmission shaft through a belt. The gears at both ends of the transmission shaft are connected to the gears in the transmission grooves through belts.

[0016] The beneficial effects of the present invention are:

[0017] 1. The surface of the skateboard forms a smooth layer. By providing inclined spiral protrusions on the outer wall of the pressing shaft, when the two pressing shafts rotate on the two side surfaces of the cardboard box, the pressing shafts can generate a downward pressure and at the same time can generate a forward driving force, thereby preventing the bottom flap of the cardboard box from opening under the action of its own elastic force;

[0018] 2. The toothed belt drives four threaded cylinders to rotate simultaneously, causing the support screw to rise and fall inside the threaded cylinder, thereby adjusting the height of the device. The rotation of the adjusting cylinder causes the adjusting cylinder to engage with the threads of the threaded rod on the inner surface of the connecting plate, thereby pushing the two pressing components to move simultaneously, thereby adjusting the distance between the two pressing components;

[0019] 3. By setting the tensioning component, when adjusting the two pressing components, the toothed belt will become loose. The setting of the tensioning component can prevent loosening; the toothed belt is located outside the gear. Under the action of the spring elasticity, the upper fixed shaft is pushed upward to tighten the toothed belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Referring to Figures 1-9 , a connecting device between a case opening and closing machine and a cartoning machine, including a support assembly 1 at the bottom, a sliding assembly 2 connected to the top of the support assembly 1, a plurality of gears 7 and a plurality of toothed belts 8 for transmission, a motor 9 for providing power, a plurality of turntables one 4 and a plurality of turntables two 5, referring to Figure 7 The support assembly 1 is composed of support rods 101, threaded cylinders 102, support screws 103, side plates 104, sliding rods 105 and a protection box 106.

The middle parts of the outer walls of the threaded cylinders 102 are all connected with gears 7, and the four gears 7 are connected by a toothed belt 8. The toothed belt 8 is connected to the turntable one 4;

[0032] Referring to Figure 4 Both sides of the sliding assembly 2 are connected with a pressing assembly 3. The sliding assembly 2 is composed of a sliding plate 201, a sliding block 202, a threaded block 203, a fixed block 204 and an adjusting cylinder 205. The surface of the sliding plate 201 is coated with a smooth coating, and both ends of the sliding plate 201 are inclined downwards;

[0033] Referring to Figure 2 The pressing assembly 3 is composed of a pressing shaft 301, a transmission groove 302, a support box 304, a connecting plate 305 and a transmission shaft 306. The outer wall of the pressing shaft 301 is provided with a spiral protrusion, and the inclination angle of the spiral protrusion is greater than 45° and less than 60°;

[0034] In the embodiment, the smooth coating is polytetrafluoroethylene, so that the surface of the sliding plate 201 forms a smooth layer. By providing an inclined spiral protrusion on the outer wall of the pressing shaft 301, when the two pressing shafts 301 rotate on the two sides of the cardboard box surface, the pressing shaft 301 can generate a downward pressure and can also generate a forward driving force, thereby preventing the bottom flap of the cardboard box from opening under its own elastic force;

[0035] Further, referring to Figure 9 The turntable one 4 is composed of a turntable, a shaft, a gear and a handle. The protection box 106 wraps around the gears 7 of the four threaded cylinders 102 and is rotatably connected to the threaded cylinders 102. A through hole is provided on one side surface of the protection box 106 and is connected to the shaft of the turntable one 4. The teeth of the turntable one 4 are in transmission connection with the toothed belt 8 at the threaded cylinder 102. The tops of the two support screws 103 on one side are both connected with a side plate 104, and two parallel sliding rods 105 are provided between the two side plates 104;

[0036] When adjusting the height, the first turntable 4 rotates, causing the gear 7 of the first turntable 4 to engage with the toothed belt 8, so that the toothed belt 8 drives the four threaded cylinders 102 to rotate simultaneously, causing the support screw 103 to rise and fall inside the threaded cylinder 102, thereby adjusting the height of the equipment;

[0037] Further, refer to Figure 5 On both sides of the lower surface of the sliding plate 201, two sliders 202 are connected. The sliders 202 are slidably connected to the sliding rod 105. In the middle of one side of the lower surface of the sliding plate 201, a threaded block 203 is connected. On one side of the threaded block 203, there are fixed blocks 204 connected to both sides of the lower surface of the sliding plate 201.

The shaft of the first turntable 4 passes through the side plate 104 and the fixed block 204 and is connected to the middle gear of the adjusting cylinder 205 through the teeth at one end;

[0038] When adjusting the distance between the two pressing components 3, by rotating the first turntable 4, the adjusting cylinder 205 is driven to rotate, so that the adjusting cylinder 205 engages with the thread of the threaded rod on the inner surface of the connecting plate 305, thereby pushing the two pressing components 3 to move simultaneously, so as to adjust the distance between the two pressing components 3;

[0039] Further, refer to Figure 1 The two pressing shafts 301 are installed in parallel. On the outer walls of the pressing shafts 301, two transmission grooves 302 are provided. Inside the transmission grooves 302, gears 7 coaxial with the pressing shafts 301 are provided. The two pressing shafts 301 on the same side are rotatably connected to a support box 304. The support box 304 surrounds the gears 7 and the toothed belt 8. At the bottom end of the support box 304, a transmission shaft 306 is rotatably connected. Between the two support boxes 304, they are connected through a connecting plate 305. On the inner surfaces of the connecting plates 305 of the two pressing components 3, they are both threadedly connected to the two ends of the inner wall of the adjusting cylinder 205 through threaded rods;

[0040] When the rotating shaft 306 rotates driven by the gear set 10, the gear 7 in the middle of the rotating shaft 306 drives the gears inside the transmission grooves 302 of the lower pressing shafts 301 through the belt. The gears 7 between the two pressing shafts 301 on the same side are driven by the toothed belt 8, so that the two pressing shafts 301 on the same side rotate in the same direction;

[0041] Further, refer to Figure 6 On the upper surface of the protection box 106, a gear set 10 is provided. At one end of the gear set 10, a motor 9 is provided. The gear set 10 is connected to the gear 7 in the middle of the transmission shaft 306 through the belt 8. The gears 7 at both ends of the transmission shaft 306 are connected to the gears 7 of the transmission grooves 302 through the belt 8;

[0042] Further, refer to Figure 6The gear set 10 consists of two shafts and four gears 7. The shafts are fixed by two vertical straight plates through hole-shaft fitting. The gears 7 on the same shaft are distributed in the middle and at one end, and the gears 7 at one end of the two shafts are just in different directions.

[0043] Through the setting of the gear set 10, the rotation directions of the pressing shafts 301 of the pressing components 3 on both sides are the same, both rotating inwardly and engaging, making the rotation directions of the pressing shafts 301 on both sides opposite.

[0044] Furthermore, referring to Figure 7 On both sides of the gear set 10, there are tensioning components 11 connected to the protection box 106. The tensioning component 11 consists of a fixed shaft 111, a limiting rod 112, a spring 113, a mounting plate 114 and a gear 7. The two fixed shafts 111 are arranged in parallel. On the upper surfaces at both ends of the lower fixed shaft 111, limiting rods 112 are fixedly connected. The limiting rods 112 penetrate through the upper fixed shaft 111. A spring 113 is arranged around the limiting rods 112. The lower fixed shaft 111 is connected to the surface of the protection box 106 through the mounting plate 114. A gear 7 is rotatably connected to the middle of the fixed shaft 111.

[0045] The tensioning component 11 is used to tension the toothed belt 8 at the gear set 10. When adjusting the two pressing components 3, it will cause the toothed belt 8 to slacken. The setting of the tensioning component 11 can avoid slackening.

[0046] When tensioning, the toothed belt 8 is located outside the gear 7. Under the elastic force of the spring 113, the upper fixed shaft 111 is pushed upward to tighten the toothed belt 8.

[0047] Furthermore, the second turntable 5 is rotatably connected to the middle of the side plate 104. The second turntable 5 consists of a turntable and a threaded rod. The threaded rod of the second turntable 5 passes through the side plate 104 and is threadedly connected to the threaded block 203.

[0048] The rotation of the second turntable 5 drives the threaded block 203 to move through the meshing of the threaded rod, and pushes the sliding component 2 and the pressing component 3 to move together.

[0049] Furthermore, locking parts 6 are provided at the connection positions of the first turntable 4 and the second turntable 5 with the side plate 104.

[0050] The locking part 6 is a U-shaped block. The U-shaped block is connected to the side plate 104 through bolts, and is locked between the two ends of the U-shaped block through threaded holes and bolts.
