Description

Technical Field

[0001] The utility model belongs to the technical field of PVC plastic production, and specifically relates to a cloth cart for drying PVC heat stabilizer. Background Art

[0002] Polyvinyl chloride (PVC) is a general-purpose plastic second only to polyethylene (PE) in mass production. It has the advantages of self-extinguishing, flame retardant, wear resistance, high strength, good electrical insulation and chemical stability, and is inexpensive. It is widely used in industry, agriculture, national defense, construction and other fields. However, PVC has a special structure and is processed under high temperature and high shear conditions. It is easy to remove HCL from the molecules and cause polymer degradation, resulting in discoloration of the product and a decrease in the mechanical properties of the product, affecting its service life. Therefore, it is necessary to add a heat stabilizer to increase its stability.

[0003] In the prior art, there is a cloth cart for drying PVC heat stabilizer with patent announcement number CN210242336U. When in use, the above patent has hanging holes corresponding to the hooks on the crossbeam, and the hooks can hook the hanging holes, so that the pallet is stopped by the taut steel cable. Even if it is pushed to cause shaking or the ground is uneven, it is not easy for the pallet to leave the cloth cart. A roller is installed at the bottom end of the column, but there are still the following shortcomings in actual use: from a practical point of view, the cloth cart is used only by the wheels at the bottom to move the whole body. After moving to the designated position, it is still fixed at the designated position by the wheels. It is easy to move due to collision in the external environment, resulting in overall instability and easy to cause safety hazards. Moreover, the pallet is fixed by tightening the steel cable, and the steel cable will be affected by wear and corrosion during use. Especially in a high temperature environment, its service life will be greatly shortened and the fixing effect is unstable.

[0004] Therefore, a fabric cart for drying PVC heat stabilizer is needed to solve the problems of overall instability caused by wheel fixation and unstable fixing effect of steel cables in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with embodiments.

[0023] See also Figure 1-4 The utility model provides a cloth cart for drying PVC heat stabilizer, comprising a base 1, a moving mechanism 2, a support column 3, a placement beam 4, a limiting mechanism 5 and a tray 6. The moving mechanism 2 is arranged inside and below the base 1, the support columns 3 are symmetrically fixedly connected to the upper four sides of the base 1, the placement beam 4 is evenly fixedly installed between the support columns 3, the limiting mechanism 5 is arranged at both ends of the placement beam 4, and the tray 6 is arranged above the placement beam 4.

The motor 201 is fixedly connected to the back of the base 1, and the output end of the motor 201 is connected to a rotating shaft, which is connected to the worm gear 202. The transmission shaft 203 passes through the worm gear 202 and is fixedly connected to the worm gear 202. The gear set 204 is symmetrically arranged at both ends of the transmission shaft 203.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the gear set 204 includes a driving bevel gear and a driven bevel gear, the driving bevel gear is fixedly connected to one end of the transmission shaft 203, the driven bevel gear is arranged below the other side of the driving bevel gear and meshes with the driving bevel gear, the threaded rod 205 is fixedly connected to the bottom of the driven bevel gear, the threaded rod 205 is rotatably connected to the inside of the base 1, the rear side of the movable plate 206 is threadedly connected to the outside of the threaded rod 205, the fixed rod 207 is fixedly connected to the inside of the base 1, and the front of the movable plate 206 is slidably connected to the outside of the fixed rod 207;

[0026] The motor 201 is provided to simultaneously drive the threaded rods 205 on both sides to rotate, thereby ensuring the synchronization of the movement of the moving plate 206 and improving the use stability of the moving mechanism 2.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the universal wheels 208 are symmetrically fixedly connected to the front and rear sides of the bottom of the moving plate 206, and the bottom surface of the base 1 is provided with a through slot larger than the universal wheels 208, and the support legs 209 are symmetrically fixedly connected to the left and right sides of the bottom surface of the base 1;

[0028] The universal wheel 208 is received in the through slot, and the bottom height of the universal wheel 208 is higher than the bottom height of the support leg 209. At this time, the universal wheel 208 is fixed to the ground through the support leg 209 to ensure the stability of the entire material distribution vehicle.

[0029] According to the above working process, it can be known that: through the setting of the moving mechanism 2, the universal wheel 208 can be used to drive the entire cloth-making cart to move to ensure the use of the cloth-making cart, and the universal wheel 208 can be folded upward and stored in the interior of the base 1. The entire cloth-making cart is fixed to the ground through the supporting legs 209, thereby improving the stability of the cloth-making cart during use.

[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the limiting mechanism 5 is composed of a sliding rod 502, a pulling block 503, a limiting block 504 and a spring 505, and grooves 501 are symmetrically opened on the left and right sides of the placement beam 4, the sliding rod 502 is slidably connected between the groove 501 and the bottom surface of the placement beam 4, the pulling block 503 is fixedly connected to the bottom surface of the sliding rod 502, and a handle is provided on the bottom surface of the pulling block 503.

[0031] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the limit block 504 is fixedly connected to the top surface of the slide bar 502, and a side of the limit block 504 close to the end of the placement beam 4 is provided with an inclined surface;

[0032] The inclined surface is provided to facilitate the tray 6 to push the limit block 504, thereby improving the practicability of the mechanism.

[0033] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the spring 505 is fixedly connected between the limit block 504 and the bottom surface of the groove 501, and the spring 505 is sleeved on the outside of the slide bar 502;

[0034] Under the elastic action of the spring 505 , the limit block 504 is driven to return to its original position, and the right angle of the limit block 504 blocks the side surface of the tray 6 , thereby fixing the position of the tray 6 .

[0035] This solution has the following working process: when in use, the tray 6 containing the stabilizer is placed above the two placement beams 4 by sliding. During the sliding process, the inclined surface of the limit block 504 is first pushed to make the limit block 504 retract into the interior of the groove 501 to avoid obstruction to the sliding of the tray 6, until the other side of the tray 6 is blocked by the right-angled surface of the limit block 504 on the other side. At this time, the limit block 504 is driven to reset under the elastic action of the spring 505, and the right-angled surface of the limit block 504 blocks the side of the tray 6, thereby fixing the position of the tray 6. When you want to pull out the tray 6, manually pull down the handle of the pull block 503 to drive the limit block 504 to move down and retract into the groove. The tray 6 can be pulled out from the inside of the groove 501, and the operation is simple and convenient. After the position of the tray 6 is fixed, it is moved to the specified position through the bottom 508, and then the motor 201 is controlled to drive the worm gear 202 to rotate, and the gear sets 204 on both sides are driven to rotate through the transmission shaft 203, and the threaded rod 205 is driven to rotate at the same time. Since the fixed rod 207 limits the rotation of the movable plate 206, the movable plate 206 is prevented from rotating with the threaded rod 205, and the movable plate 206 can be driven to move upward, and the universal wheel 208 below is driven to move upward until the bottom surface height of the universal wheel 208 is higher than the bottom surface height of the support leg 209. At this time, it is fixed to the ground through the support leg 209 to ensure the stability of the entire cloth distributing vehicle.

[0036] In summary: through the provided moving mechanism 2, the entire fabric trolley can be driven to move through the universal wheel 208 to ensure the use of the fabric trolley, and the universal wheel 208 can be folded upward and stored in the inside of the base 1. The entire fabric trolley is fixed to the ground through the supporting legs 209, thereby improving the stability of the fabric trolley during use; through the provided limiting mechanism 5, the tray 6 can be fixed between the two limiting blocks 504 to ensure the stability of the tray 6 during the movement, and it is also convenient for the staff to pull out the tray 6 on either side, thereby improving the practicality of the fabric trolley.
