UTILITARIAN CONTENT

[0004] In order to make up for the above shortcomings, the utility model provides a kind of cold bed, to improve the problem of manual handling speed in prior art is relatively slow, so as to affect the rhythm of entire production process, and then reduce production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling bed, comprising a cooling bed body, a conveyor belt installed on the front side of the outer wall of the cooling bed body, a hollow block fixedly connected to the rear side of the outer wall of the cooling bed body, sliding short blocks slidably connected to the left and right sides of the inner wall of the hollow block, a spring one fixedly connected to the left and right sides of the bottom of the inner wall of the hollow block, the top of the spring one fixedly connected to the bottom of the sliding short block, a spring two fixedly connected to the outer wall of the hollow block, a piston rod fixedly connected to the top of the spring two, and the piston rod having a piston rod on the left and right sides of its outer wall. Elastic pull ropes are fixedly connected to both sides. The other end of the outer wall of the elastic pull rope is fixedly connected to the top of the sliding short block. A piston cylinder is fixedly connected to the bottom of the inner wall of the hollow block. A vent hole is opened at the bottom of the outer wall of the piston cylinder. The outer wall of the piston rod is slidably connected to the inside of the piston cylinder. A top plate is fixedly connected to the top of the piston rod. Hydraulic push rods are fixedly connected to the left and right sides of the front end of the outer wall of the cooling bed. Cooling mechanisms are installed on the left and right sides of the outer wall of the cooling bed. The cooling mechanisms are used to dissipate heat and cool different positions on the cooling bed where the workpiece is placed.

[0006] The above technical solution involves using a hydraulic push rod to push the cooled workpiece off the cooling bed. The workpiece first lands on the top plate, which is connected to a piston rod that slides between itself and the piston cylinder. When the workpiece lands on the top plate, the top plate is pressed downwards, causing the piston rod to slide downwards within the piston cylinder. Elastic ropes are fixedly connected to both sides of the piston rod, with the other end of each rope connected to a sliding block. As the piston rod moves downwards, the elastic ropes pull the sliding block downwards along the inner wall of the hollow block, compressing spring one for buffering and stress relief. Simultaneously, spring two on the outer wall of the hollow block is also compressed. A vent hole is located at the bottom of the outer wall of the piston cylinder. During the downward sliding of the piston rod, air inside the piston cylinder is slowly discharged through the vent hole, providing further buffering and reducing the impact force when the workpiece falls, thus achieving automatic unloading.

[0007] As a further description of the above technical solution:

[0008] The cooling mechanism includes an L-shaped plate, which is equidistantly installed on the left and right sides of the outer wall of the cooling bed. A motor is fixedly connected to the top of the L-shaped plate, and a gear ring is fixedly connected to the top of the L-shaped plate. A drive gear is fixedly connected to the output end of the motor, and a driven gear is meshed inside the gear ring. The drive gear and the driven gear mesh together.

Fans are fixedly connected to the left and right sides of the bottom of the T-shaped plate.

[0009] The above technical solution involves a motor driving the output gear to rotate. Since the driving gear meshes with the driven gear, its rotation causes the driven gear to rotate inside a gear ring, which is fixed to the top of an L-shaped plate. The driven gear, meshing with the gear ring, rotates along its interior. A T-shaped plate is fixedly connected to the bottom of the driven gear, rotating along with it. The outer wall of the T-shaped plate slides against the interior of a U-shaped block, which is fixed to the outer wall of a long sliding rod. The long sliding rod slides in the middle of a long short plate. As the T-shaped plate rotates, its rotation is converted into a back-and-forth sliding motion of the long sliding rod on the long short plate. Then, a fan starts operating, generating airflow to cool the workpiece on the cooling bed. The long sliding rod's linear reciprocating motion causes the T-shaped plate and fan to also reciprocate linearly, allowing the fan to cool different parts of the workpiece placed on the cooling bed.

[0017] A screw is threadedly connected to the lower left side of the outer wall of the L-shaped plate on the left, and a hook is threadedly connected to the outer wall of the screw.

[0018] The above technical solution allows for the convenient hanging of tools used and cleaned daily for future use.

[0019] As a further description of the above technical solution:

[0021] The above technical solution allows for the convenient storage of tools used daily and for maintenance through sliding drawers inside the hollow box.

[0022] As a further description of the above technical solution:

[0023] A handle is fixedly connected to the left side of the outer wall of the drawer, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0024] The above technical solution provides a handle fixedly connected to the left side of the outer wall of the drawer, which facilitates the use of the drawer by staff.

[0025] As a further description of the above technical solution:

[0026] The bottom of the cooling bed is fixedly connected with multiple support rods at equal intervals, and the bottom end of each support rod is fixedly connected with a foot pad.

[0027] Through the above technical solution, the foot pads fixedly connected to the bottom of the support rod can absorb the vibration generated by the cooling bed during operation and play a buffering and protective role.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the workpiece is pushed from the cooling bed to the top plate by opening the hydraulic push rod. The top plate is connected to the piston cylinder through the piston rod. When the workpiece falls to the top plate, the piston rod slides down, which drives the elastic pull rope and the sliding block to compress the first and second springs for buffering and force release. The vent hole at the bottom of the piston cylinder allows air to be slowly discharged, further buffering the impact force of the workpiece falling, realizing automatic unloading. This avoids the problem of slow manual handling affecting the rhythm of the entire production process and thus reducing production efficiency.

[0030] 2. In this utility model, after the motor is started, the driving gear rotates and drives the driven gear, causing the T-shaped plate and the fan to reciprocate along the gear ring and the long short plate, thereby generating wind to dissipate heat from the workpiece. This allows the fan to dissipate heat and cool different positions of the workpiece placed on the cooling bed, improving the uniformity and effectiveness of cooling. Attached Figure Description

A conveyor belt 6 is installed on the front side of the outer wall of the cooling bed body 1. A hollow block 3 is fixedly connected to the rear side of the outer wall of the cooling bed body 1. Sliding blocks 21 are slidably connected to the left and right sides of the inner wall of the hollow block 3. Spring 1 22 is fixedly connected to the left and right sides of the bottom of the inner wall of the hollow block 3. The top of spring 1 22 is fixedly connected to the bottom of the sliding blocks 21. When the sliding blocks 21 on both sides are pressed down by pressure, they will squeeze spring 1 22 to perform the initial buffering and force release function. Spring 23 is fixedly connected to the outer wall of the hollow block 3. A piston rod 20 is fixedly connected to the top of spring 23. Elastic pull ropes 19 are fixedly connected to the left and right sides of the outer wall of the piston rod 20.

[0041] Specifically, after the workpiece has cooled, the hydraulic push rod 5 is activated to push the cooled workpiece off the cooling bed 1. The falling workpiece first lands on the top plate 4. A piston rod 20 is connected below the top plate 4 and is slidably connected to the piston cylinder 24. Therefore, when the workpiece lands on the top plate 4, the top plate 4 is subjected to pressure and moves downwards, causing the piston rod 20 to slide downwards within the piston cylinder 24. Elastic pull ropes 19 are fixedly connected to both sides of the piston rod 20, and the other end of the elastic pull ropes 19 is connected to the sliding block 21. When the piston rod 20 moves downwards, it pulls the sliding block 21 downwards along the inner wall of the hollow block 3 via the elastic pull ropes 19, compressing the first spring 22. The first spring 22 buffers and releases the pressure. Simultaneously, the second spring 2 on the outer wall of the hollow block 3... 3 is also compressed. The bottom of the outer wall of the piston cylinder 24 is provided with a vent hole 25. During the downward sliding of the piston rod 20, the air in the piston cylinder 24 is slowly discharged through the vent hole 25, which plays a role in buffering again and reducing the impact force when the workpiece falls, so as to realize automatic unloading. Multiple support legs 7 are fixedly connected at equal intervals at the bottom of the conveyor belt 6. The bottom end of the support legs 7 is fixedly connected to the universal wheel 8. The support legs 7 at the bottom end of the conveyor belt 6 and the universal wheel 8 at the bottom end can facilitate the workers to transfer the conveyor belt 6 to different places for use. The left side of the outer wall of the left L-shaped plate 201 is threaded with a screw 17. The outer wall of the screw 17 is threaded with a warning sign 18. The warning sign 18 on the left side of the left L-shaped plate 201 can play a role in warning and reminding the surrounding personnel and operators.

[0042] Reference Figure 2 , Figure 5 and Figure 6The cooling mechanism 2 includes an L-shaped plate 201, which is equidistantly installed on the left and right sides of the outer wall of the cooling bed 1. A motor 202 is fixedly connected to the top of the L-shaped plate 201, and a gear ring 203 is fixedly connected to the top of the L-shaped plate 201. A drive gear 209 is fixedly connected to the output end of the motor 202. A driven gear 210 is meshed inside the gear ring 203. The drive gear 209 and the driven gear 210 are meshed together. Multiple long short plates 206 are fixedly connected to the top of the L-shaped plate 201 at equal intervals. A long slide rod 205 is slidably connected to the middle of the long short plate 206. The long short plates 206 serve to fix the long slide rod 205 and limit the sliding direction of the long slide rod 205. A U-shaped block 204 is fixedly connected to the outer wall of the long slide rod 205. A T-shaped plate 211 is fixedly connected to the bottom of gear 210. The outer wall of T-shaped plate 211 is slidably connected to the inside of U-shaped block 204. A battery 207 is fixedly connected to the middle of the bottom wall of T-shaped plate 211. Fans 208 are fixedly connected to the left and right sides of the bottom of T-shaped plate 211. Fans 208 serve to blow air and dissipate heat. A screw 15 is threadedly connected to the lower left side of the outer wall of left L-shaped plate 201. A hook 16 is threadedly connected to the outer wall of screw 15.

A drawer 11 is slidably connected inside the hollow box 12. The drawer 11 slidably connected inside the hollow box 12 can be used to store tools for daily use and maintenance.

[0043] Specifically, the motor 202 drives the drive gear 209 at the output end to rotate. Since the drive gear 209 meshes with the driven gear 210, when the drive gear 209 rotates, it drives the driven gear 210 to rotate inside the gear ring 203. The gear ring 203 is fixed to the top of the L-shaped plate 201. Under the meshing action with the gear ring 203, the driven gear 210 rotates along the inside of the gear ring 203. The bottom end of the driven gear 210 is fixedly connected to a T-shaped plate 211, which rotates together with the driven gear 210. The outer wall of the T-shaped plate 211 is slidably connected to the inside of the U-shaped block 204, and the U-shaped block 204 is fixed to the outer wall of the long slide rod 205. The long slide rod 205 slides in the middle of the long short plate 206. When the T-shaped plate 211 rotates, it converts the rotation of the T-shaped plate 211 into the rotation of the long short plate 206. The long slide bar 205 slides back and forth on the long short plate 206 in a cyclical motion. Then the fan 208 starts to run, generating airflow to dissipate heat from the workpiece on the cooling bed 1. Because the long slide bar 205 makes linear reciprocating motion, it will drive the T-shaped plate 211 and the fan 208 to also make linear reciprocating motion, so that the fan 208 can dissipate heat and cool different positions of the workpiece placed on the cooling bed 1. The lower left side of the outer wall of the left L-shaped plate 201 is threaded with a screw 15. The outer wall of the screw 15 is threaded with a hook 16.

The handle 13 fixedly connected to the left side of the outer wall of the drawer 11 facilitates the use of the drawer 11 by the staff. Multiple support rods 10 are fixedly connected at equal intervals to the bottom of the cooling bed 1. Foot pads 9 are fixedly connected to the bottom end of the support rods 10.

[0045] Specifically, a handle 13 is fixedly connected to the left side of the outer wall of the drawer 11, and an anti-slip sleeve 14 is fixedly connected to the outer wall of the handle 13. The handle 13 fixedly connected to the left side of the outer wall of the drawer 11 facilitates the use of the drawer 11 by the staff. Multiple support rods 10 are fixedly connected at equal intervals to the bottom of the cooling bed 1. Foot pads 9 are fixedly connected to the bottom end of the support rods 10. The foot pads 9 fixedly connected to the bottom end of the support rods 10 can absorb the vibration generated by the cooling bed 1 during operation and play a buffering and protective role.

[0046] Working principle: After the workpiece has cooled, the hydraulic push rod 5 is activated to push the cooled workpiece off the cooling bed 1. The falling workpiece first lands on the top plate 4. A piston rod 20 is connected to the bottom of the top plate 4 and is slidably connected to the piston cylinder 24. Therefore, when the workpiece lands on the top plate 4, the top plate 4 is subjected to pressure and moves downwards, causing the piston rod 20 to slide downwards within the piston cylinder 24. Elastic pull ropes 19 are fixedly connected to the left and right sides of the piston rod 20. The other end of the elastic pull ropes 19 is connected to a sliding block 21. As the piston rod 20 moves downwards, it will... The sliding block 21 is pulled downward by the elastic rope 19 and slides down the inner wall of the hollow block 3, compressing the first spring 22. The first spring 22 buffers and releases the force. At the same time, the second spring 23 on the outer wall of the hollow block 3 is also compressed. The bottom of the outer wall of the piston cylinder 24 has a vent hole 25. During the downward sliding of the piston rod 20, the air in the piston cylinder 24 is slowly discharged through the vent hole 25, which buffers again and reduces the impact force when the workpiece falls. This realizes automatic unloading and avoids the problem of slow manual handling affecting the rhythm of the entire production process and thus reducing production efficiency.

[0047] The motor 202 drives the drive gear 209 at the output end to rotate. Since the drive gear 209 meshes with the driven gear 210, its rotation causes the driven gear 210 to rotate inside the gear ring 203, which is fixed to the top of the L-shaped plate 201. The driven gear 210 rotates along the inside of the gear ring 203 due to its meshing with the ring. A T-shaped plate 211 is fixedly connected to the bottom of the driven gear 210, rotating along with it. The outer wall of the T-shaped plate 211 is slidably connected to the inside of the U-shaped block 204. 4. It is fixed to the outer wall of the long slide bar 205. The long slide bar 205 slides in the middle of the long short plate 206. When the T-shaped plate 211 rotates, it will convert the rotation of the T-shaped plate 211 into the long slide bar 205 sliding back and forth on the long short plate 206. Then the fan 208 starts to run, generating wind to dissipate heat from the workpiece on the cooling bed 1. Since the long slide bar 205 makes linear reciprocating motion, it will drive the T-shaped plate 211 and the fan 208 to also make linear reciprocating motion, so that the fan 208 can dissipate heat and cool different positions of the workpiece placed on the cooling bed 1, improving the uniformity and effect of cooling.
