Technical Field
[0001] This utility model relates to the field of transport clamp technology, specifically to a card clamp for separating rubber stopper raw materials. Background Technology
[0002] In the processing of rubber stoppers, ensuring the flatness of the raw material sheets is crucial. Uneven raw material sheets result in uneven stress during stamping, leading to quality problems such as dimensional deviations and poor sealing, which in turn affect compatibility with pharmaceuticals and may even cause drug contamination. To address this issue, those skilled in the art have actively explored solutions. For example, Chinese Patent Publication No. CN205614360U discloses a fixture for processing multiple row-position inserts. However, this solution still has shortcomings: it is difficult to maintain the flatness of the raw material sheets before processing; during storage or transportation, the raw material sheets are prone to curling due to heat loss, reducing stamping quality and increasing scrap rate and cost; the positioning of the raw material sheets cannot be observed during placement, easily leading to deviations and affecting efficiency and quality; separating the raw material sheets is difficult, labor-intensive, and may cause damage; and transportation efficiency is also low. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a card clamp for separating rubber stopper raw materials.
[0004] The technical solution adopted in this utility model is as follows: A card clamp for spacing rubber stopper materials includes at least two overlapping clamp bodies, with a counterweight applied to the upper surface of each clamp body; wherein the clamp body includes the following parts: The clamping part is arranged in a U-shaped groove, and several locking elements are arranged at equal intervals on it; The spacer is arranged in the form of a transparent sheet, and several layers of spacers are inserted into the U-shaped groove of the clamping part and fixed by a locking member; the spacer includes at least an upper spacer I and a lower spacer II, and a raw material sheet for producing rubber stoppers is clamped between spacer I and spacer II. The material has a spacer between adjacent raw material pieces, and a counterweight is applied to the raw material piece along with the extrusion force of the raw material piece above it.
[0005] This technical solution achieves reliable spacing and fixation of raw material sheets through a combination of multi-layered clamping bodies and counterweights. The overall structure maintains the flatness of the raw material sheets before processing, resists curling caused by heat loss, and ensures the stamping quality of the rubber stoppers. Specifically, the U-shaped groove clamping part cooperates with the locking part to fix the stacked spacing parts; the transparent spacing parts facilitate observation of the placement position of the raw material sheets; the counterweights apply additional pressure, which causes the raw material sheets to form a uniform stress layer in the vertical direction, thereby ensuring that the initial state of the raw material sheets is controllable before processing.
[0006] In addition, the card holder for separating rubber stopper materials proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the spacer portion is made of a transparent film, and the size of the transparent film is larger than the size of the raw material sheet.
[0007] In this technical solution, the transparent film is made into a spacer, allowing operators to check the status of the raw material sheet at any time, promptly detect and address issues such as displacement and deformation; by using a transparent film larger than the raw material sheet, sufficient buffer area is reserved for adjusting the position of the raw material sheet.
[0008] According to one embodiment of the present invention, the surface of the transparent film is provided with an anti-adhesion layer to facilitate the removal of the raw material sheet.
[0009] This technical solution utilizes the lubricating properties of the anti-adhesion layer to reduce the friction and adhesion between the film and the raw material sheet, thereby enabling rapid and complete separation of the raw material sheet and the film with a small amount of external force when the raw material sheet needs to be separated.
[0010] According to one embodiment of the present invention, the surface of the transparent film is printed with dotted lines to guide the placement area of the raw material sheet.
[0011] This technical solution utilizes the visual guidance of dotted lines to provide operators with clear placement references, enabling them to quickly and accurately place the raw material slices in the designated area, ensuring the standardization and consistency of raw material slice placement.
[0012] According to one embodiment of the present invention, the spacer I is the top layer spacer, which is coated with markings to distinguish different clamp bodies.
[0013] This technical solution utilizes the visual differences in markings to enable operators to quickly and accurately identify and distinguish each fixture body, avoiding misuse and mixing of fixtures.
[0014] According to one embodiment of the present invention, the clamp bodies are stacked on a transport vehicle in an overlapping manner, and a counterweight is placed in the middle of the top clamp body. The transport vehicle is used to transport the rubber stopper raw materials in batches.
[0015] In this technical solution, the overlapping and stacking method makes full use of the transport vehicle space, allowing more rubber stopper raw materials to be transported at once, reducing the number of transport trips and improving overall transport efficiency.
[0016] Compared with the prior art, this utility model has the following advantages: (1) Problems such as displacement can be detected in time through the transparent partition. The partition is coated with an anti-adhesion layer to facilitate the separation of the raw material sheet. The dotted line markings of the partition ensure proper placement. The counterweight ensures that the raw material sheet is evenly stressed in the vertical direction, maintaining its flat state before processing and ensuring stamping quality.
[0017] (2) The clamps are stacked on the transport vehicle to make full use of space, allowing more rubber stopper raw materials to be transported at once, reducing the number of transport trips, effectively improving overall transport efficiency and reducing transport costs.

Among them, a spacer is provided between adjacent raw material sheets 15, and the weight of the counterweight 2 and the extrusion force of the raw material sheet 15 above it are applied to the raw material sheet 15.
[0023] This technical solution achieves reliable spaced fixation of the raw material sheet 15 through the combination of a multi-layer clamp body 1 and a counterweight 2. The overall structure maintains the flatness of the raw material sheet 15 before processing, resists curling caused by heat loss, and ensures the stamping quality of the rubber stopper. Specifically, the U-shaped groove clamping part 11 cooperates with the locking part 12 to fix the stacked spaced parts; the transparent spaced parts facilitate observation of the placement position of the raw material sheet 15; the counterweight 2 applies additional pressure, which makes the raw material sheet 15 form a uniform force layer in the vertical direction, thereby ensuring that the initial state of the raw material sheet 15 is controllable before processing.
[0024] In addition, the card holder for separating rubber stopper materials proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the spacer portion is made of a transparent film, and the size of the transparent film is larger than the size of the raw material sheet 15.
[0025] In this technical solution, the transparent film is made into a spacer, allowing operators to check the status of the raw material sheet 15 at any time, promptly detect and handle problems such as displacement and deformation; by using a transparent film larger than the raw material sheet 15, sufficient buffer area is reserved for adjusting the position of the raw material sheet 15.
[0026] According to one embodiment of the present invention, the surface of the transparent film is provided with an anti-adhesion layer to facilitate the detachment of the raw material sheet 15.
[0027] This technical solution utilizes the lubricating properties of the anti-adhesion layer to reduce the friction and adhesion between the film and the raw material sheet 15, thereby enabling the rapid and complete separation of the raw material sheet 15 from the film with a small amount of external force when the raw material sheet 15 needs to be detached.
[0028] According to one embodiment of the present invention, the surface of the transparent film is printed with dotted lines to guide the placement area of the raw material sheet 15.
[0029] This technical solution utilizes the visual guidance of dotted lines to provide operators with clear placement references, enabling them to quickly and accurately place the raw material slices 15 in the designated area, ensuring the standardization and consistency of the placement of the raw material slices 15.
[0030] According to one embodiment of the present invention, the spacer portion I13 is the top layer spacer portion, which is coated with markings to distinguish different clamp bodies 1.
[0031] This technical solution utilizes the visual difference characteristics of the markings to enable operators to quickly and accurately identify and distinguish each fixture body 1, avoiding misuse and mixing of fixtures.

[0034] The usage process of the above embodiments is as follows: like Figures 1 to 2 As shown, initially, the U-shaped groove clamping part 11 cooperates with the locking part 12 to firmly clamp the multi-layered spacer part using the mechanical fixing principle, forming the basic structure. When in use, the spacer part is opened to place the raw material sheet 15, which is based on the layered operation principle to achieve the orderly placement of the raw material sheet 15. The transparent spacer part uses optical principle to facilitate the operator to observe the state of the raw material sheet 15. The transparent film with a size larger than the raw material sheet 15 reserves a buffer area, which is based on the space reservation principle to deal with placement deviations. The anti-adhesion coating uses the lubrication principle to reduce friction and adhesion, making it easy for the raw material sheet 15 to detach. The dotted line marking uses the visual guidance principle to ensure standardized placement. Multiple clamp bodies 1 are stacked on the transport vehicle and counterweight 2 is added. On the one hand, the space optimization principle is used to improve the transportation efficiency, and on the other hand, the pressure is applied by the counterweight 2 to make the raw material sheet 15 uniformly stressed in the vertical direction, maintain flatness, resist heat loss and curling, and ensure stamping quality.
